The 3 BIG questions about the Sonicare DiamondClean

If you are short of time, the answers to the following 3 questions should let you know all you need to about the Sonicare DiamondClean electric toothbrush.  If we have missed something, let us know in the comments.

If you want more detail, you can read our full Sonicare DiamondClean review further down the page or watch our video review.

1. Is there anything drastically wrong with this toothbrush?

No, far from it.  It offers great performance and cleaning.

Very good battery life, available in a range of colours, a smart travel case, but the minimalist design does work against it somewhat.

We have given a rating of 4/5 to the DiamondClean.

2. Which other brushes should I consider?

Ultimately it depends on what you require of an electric toothbrush.

If you want a solid performing option, without lots of extras, then consider the ProtectiveClean 4300.

If you really want the best, with features such as in the case charging, then the DiamondClean Smart is the brush you should consider.

Philips Sonicare DiamondClean Review (3rd Generation)

And now for a bit more detail….

The DiamondClean is the premium range of brushes from Sonicare.

Now in its 3rd generation, it is the brush that combines all the best cleaning modes with elegant design and box contents.

As a result, it is also one of the most expensive.

An excellent brush, it is not faultless, but the strong cleaning performance, battery life and variety of colour options set this brush up to stand out from the competition.

Variants of this toothbrush

Apologies but this is about to get a bit confusing, but hopefully, I can explain in a way that makes sense.

The DiamondClean range has existed for a few years and at the end of 2016, an updated version was released.  This 3rd generation model replaces the 2nd generation model that launched in late 2014.

Over time the 2nd generation model will be phased out, with many larger retailers now selling only the newer model, but be aware that 2 models exist and you probably want to opt for the newer 3rd generation model; although you may likely pick up a good deal on the older 2nd generation box.

What’s the difference between the 2nd and 3rd generation models?

The key differences between the 2014 and 2016 model of the Sonicare DiamondClean brushes are as follows:

  • The 2nd gen model came with a charging glass, whereas the 3rd gen comes with a plastic charging stand (looks like glass).  The 3rd gen works in a similar way but keeps the brush upright, whereas with the 2nd gen model the brush was tilted within the glass and other items could be put in the glass too.
  • The provided brush head has changed.  Despite the model name being ‘DiamondClean’ the 3rd generation brush actually comes supplied with an ‘AdaptiveClean’ brush head.
  • Polish cleaning mode was available on the 2nd gen model, but this has been replaced with Deep Clean on the 2016 model.
  • The Amethyst colour edition is not available in the 3rd generation.

The different coloured models

With both the 2nd and 3rd gen models, various colour options exist.  Each one has a different model number, so it is probably worth knowing the difference.

  • 2nd Generation
    • White – HX9331/04
    • Black – HX9351/04
    • Pink – HX9361/67
    • Rose Gold – HX9311/04
    • Amethyst – HX9371/04
  • 3rd Generation
    • White – HX9331/32
    • Black – HX9351/52
    • Pink – HX9361/62
    • Rose Gold – HX9391/92

All being well you are now clear on the different models and how they compare.

This review will focus primarily on the newest 2016/3rd generation model but will make reference to the 2nd generation for comparison sake and rounder explanation on the brush.

What’s in the box?

  • Philips Sonicare DiamondClean rechargeable toothbrush
  • Charging stand
  • 1 x Standard AdaptiveClean brush head
  • Travel case
  • Travel case charger
  • Travel cap
  • Documentation

Key Features

  • Sonic cleaning action
  • 5 different cleaning modes
  • Built-in rechargeable battery
  • 3 week battery life
  • 2 minute timer
  • 30 second pacer
  • Automatic power off

Pro & Cons

Here are what I consider to be the pros and cons of the Sonicare DiamondClean.

The Positives

  • 5 cleaning modes – Whilst most generally stick to just one cleaning mode, ‘Clean’ this brush caters for different user needs with 5 useful and distinctly different modes.
  • Battery life – An impressive 3 weeks of battery life is available from the fully charged Lithium Ion battery and it is simple and easy to charge.
  • Travel case – Great for protection when being transported, the addition of in the case charging via USB is a real bonus for the more connected traveller.
  • Automatic power off – It is a very simple, yet effective means of conserving battery power that psychologically saves more effort than you think.
  • Brush head – Engineered for really giving your teeth a good clean and achieving an oral healthcare routine that your dentist would be proud of.

The Negatives

  • Design – The fairly slim profile looks great, but the cleaning modes are virtually impossible to read unless the brush is powered on and the brush is a little more slippery than some.
  • Box contents – Whilst the box contents is not bad, it would have been nice to see some additional brush heads included.
  • Charging stand – Now all plastic rather than glass. More practical but could be a better fit and design.
  • Bluetooth – Arguably a gimmick for some, for a flagship brush I think it could have included it to ensure it is more in line with the competitors products.
  • Travel case power connection – MiniUSB, the charging port of choice on the travel case is dated. At worst this should be MicroUSB or even the new and even more future proofed USB Type-C.

Design, usability, clean & general use

Sleek and stylish are just two words that I could use to describe this brush.

I really like that this brush comes in an array of colour options, making it more appealing to a wider audience.  It is a shame that the Amethyst colour option has not made its way to the latest generation, but hey it is nice to have the option of white, black, pink and rose gold.

The white colour option is typically the most popular.

Philips Sonicare DiamondClean Review 1

Smooth to the touch there are no lights or unsightly icons or buttons on the DiamondClean brush handle.  In fact I would argue that Sonicare have almost gone too minimal.

Whilst the handles have more of a matte finish to them and are not exactly slippery in hand, there are no raised grips or textured surfaces at all.

Running down the handle there is the Sonicare logo in a grey colour.

Below this is the power button, which has a depression that the thumb fits comfortably into.  It is not easy to accidentally press this, but does not take too much force to activate.

Philips Sonicare DiamondClean Review 2

There is a green power icon on the button to indicate that it is this, but that icon is not backlit.

Under the power buttons are the names of the cleaning modes and the battery status icon.

These cleaning modes are lit when selected and the brush is running, as is the battery icon.  With the power off you can hardly see these names in the handle at all.

To access the different modes, you need to power on the brush and then press again, possibly multiple times to access the cleaning mode required.

The cleaning modes run in this order:

  • Clean (Press power button once)
  • White (Press power button twice, once to turn on and then again to change the mode)
  • Sensitive (Press power button three time, once to turn on and twice to change the mode)
  • Gum Care
  • Deep Clean

The brush will remember the last cleaning mode used, if the brush automatically powers off at the end of the cleaning cycle.

So if deep clean was the last mode used and the brush turned itself off, when you next power it on, it will start on deep clean so you will not be required to five presses like you might if it was brand new and never before used.

In principle this is good and the brush looks smart, but you have to actually power the brush on to see what cleaning mode it is on.  So if you can’t remember what you last used, power it on to take a look, but remember to do this before adding toothpaste!

I get the minimal look and design but for me this has gone past the point of practicality.

Philips Sonicare DiamondClean Review 3

Sorry I have to knock points off for Philips here.  On other models they have another button to cycle through modes.  I get the idea why, but I will take function over design in this instance.

This is perhaps worsened, if like many the brush handle is shared between users.  You constantly need to check and maybe cycle through the modes.  The redeeming feature is that 5 cleaning modes makes this applicable for a wide array of users.

The different cleaning modes, which we summarise below but explain in more detail here, last for differing amounts of time and deliver different frequencies and brush strokes to the teeth to deliver a different clean.

A little more detail on each:

  • Clean – The ultimate in plaque removal (Standard mode). Lasts for 2 minutes.
  • White – Whitening mode of 2 minutes to remove surface stains, plus an additional 30 seconds to brighten and polish your front teeth. Lasts for 2 minutes and 30 seconds.
  • Sensitive – Extra gentle mode for sensitive teeth and gums. Lasts for 2 minutes
  • Gum care – Complete mode combines Clean mode with an additional minute to gently stimulate and massage your gums to improve gum health. Lasts for 3 minutes.
  • Deep Clean – Provides an invigorating deep massage to deliver an exceptionally clean experience. Lasts for 3 minutes.

See full details in our guide on how to clean your teeth with an electric toothbrush, but as an overview: move the brush head slowly and gently across the teeth in a small back and forth motion so the longer bristles reach between your teeth. Do not scrub like a manual toothbrush. Apply light pressure to maximise Sonicare’s effectiveness and let the Sonicare do the brushing for you.

Compared to a manual brush the DiamondClean with the provided AdaptiveClean head could remove up to 10 times more plaque and leave you with healthier gums in just two weeks.

This brush has a quadpacer.  This is an interval timer that beeps and briefly pauses to remind you to brush the 4 sections of your mouth. Depending on the brushing mode you have selected, the quadpacer beeps at different intervals during the brushing cycle.

It is the timer, that at the end of the brushing cycle selected will turn the brush off to conserve power and alert you to the clean being complete.

If you want to continue, just press the power button again.

Philips Sonicare DiamondClean Review 4

This brush offers up to 3 weeks battery life from the built-in battery, but more on that later.

The brush does a great job of cleaning and at no point did I feel the brush had done a poor job, my teeth felt clean and refreshed after each clean.

On the base of the brush is a silver plate.  This is the inductive charging panel.  There is no recess for a prong to charge the brush, like there are with many other models.

Just sit this brush on the charging stand provided or in the case and the charge is transferred through this plate.

At the top of the brush handle is the detachable and interchangeable brush head.

Philips Sonicare DiamondClean Review 5

Perhaps rather oddly, the DiamondClean brush now comes with a standard sized AdaptiveClean brush head with this 3rd generation model.  The 2nd generation came with a DiamondClean head. I am not sure why Philips have changed this, possibly because the AdaptiveClean is a better all round head and does not focus primarily on whitening.

The good news is that there are a range of brush heads available that are compatible with the DiamondClean handle.

Your options include:

  • DiamondClean – Superior cleaning, improved gum health and whiter teeth in just one week
  • InterCare – Extra long bristles to reach plaque in hard to reach areas between teeth
  • ProResults – All round cleaning with contoured profile to naturally fit the profile of the teeth and improve overall plaque removal
  • ProResults Gum Health – Densely-packed, high-quality tufts easily reach teeth at the back of the mouth. Also features a gentle trim profile to cushion teeth for an extra gentle brushing experience.
  • Sensitive – Ultra-soft bristles for gentle, effective cleaning. Also features special trim profile to cushion teeth for a gentler brushing experience.

Any of these can be purchased separately.  The pack size and the head size does differ depending on the one you opt for.  There is the standard size and the compact option for the harder to reach areas of the mouth.

With all the colour options, except black, a white coloured AdaptiveClean brush head is provided.  With the black, you get in the box you get a colour matched AdaptiveClean brush head.  This is great, but at the time of writing you cannot purchase the AdaptiveClean heads in black colour, so if you need to replace it, back to white.  I guess they will be launched at some point as to date only the DiamondClean brush heads have a black colour option.  So as nice as it is, if you want to keep the colour match you are somewhat limited.

The heads are easily replaced, pull off and push on.  Remember to change them every 3 months, sooner if the bristles are worn of the reminder bristles have faded.

The reminder bristles are the blue coloured bristles which over a typical 3 month period will fade from a relatively strong blue to white colour.  If they turn white, replace the head.

For more information see our complete guide on Sonicare replacement heads.

Some users share a brush handle with family members or a partner for convenience and to extend the value. Given the various cleaning modes and specialised heads, it would be nice to include or have available some form of brush head storage compartment to allow storage.  Third party options do exist.

Another neat feature of this brush is the ‘Easy-Start’ option.

Designed specifically for first time users, to help them ease into using an electric toothbrush. The Easy-start feature gradually increases the sonic power over the first 14 brushing sessions.

Brushing must last at least 1 minute to properly advance through this ramp-up cycle.

Easy-start can be deactivated.  To do so, just place the handle in the plugged-in charging base or charging travel case, then push and hold the on/off button for 2 seconds; 1 beep indicates the Easy-start feature has been deactivated; 2 beeps indicate the feature has been reactivated.

The brush itself is water resistant, but not water proof.  This means if you rinse it under the tap and it gets wet, don’t worry too much.  However, the brush is not designed to be used in or under water, so avoid using in the shower or bath.  A rinse and a damp cloth is fine for cleaning.

Philips Sonicare DiamondClean Review 6

With 21 days of battery life this slim profiled brush handle is really quite impressive, yet it comes with 2 charging solutions in the box.  The first is a glass charging stand and the other is a travel case.  I explain more about each of these in the ‘Battery’ section of the review below.

A neat addition, I particularly like the travel case.

The case is sort of colour matched to the brush, although the case with the white brush is silver and is a rigid construction with a soft touch material coating over the harder inner shell.  This not only provides excellent protection to the brush handle and up to 2 brush heads, it also looks smart.

It is not small, but then again you do not expect it to be.  The case closes magnetically too, which is a nice touch.  It is easy to open again so the magnets are not that strong.

The brush can be charged in the case which is great and it can be connected to mains power or a USB socket on your computer or charger, must like a smartphone.  It is a shame unlike a smartphone Sonicare stuck with a dated connector, more on that below too.

2 features that are in my opinion missing is a pressure sensor and Bluetooth connectivity.

Philips Sonicare DiamondClean Review 3

A pressure sensor is not that common on Sonicare brushes, but is on Oral-B.  As the name implies if too much pressure is applied during cleaning a light is illuminated to alert you and you can reduce this so as not to do damage to the teeth.  You soon learn, but the inclusion of such would help new users I think.

To be fair the brush will make a straining sound if too much pressure is being used, but you need to listen out for that.

Now the second feature I believe they are missing is Bluetooth connectivity.  It can be argued quite convincingly that this is a gimmick and not needed, but what’s the harm in including it?  Its use then becomes optional.

If you have missed this whole Bluetooth in a toothbrush thing then allow me to briefly explain.

Some brush handles include this and via an app available from the relevant app stores, your smartphone communicates with the brush to show you in real-time, cleaning time, mode and performance and then logs this for future reference.

For years we have done without the need for such, but as millennials adopt electric toothbrushes there is an expectation.

Sonicare have actually overall probably done a better job of implementing it that Oral-B have, yet Oral-B have it on a lot more models than Philips.

Given this brush is competing with the Genius 9000, it is an omission that will favour Oral-B.

So, overall it is pretty good going for the DiamondClean.

For that added extra peace of mind, the brush comes with a 2 year warranty that covers mechanical faults like the battery no longer charging or the power button not working.  It does not cover user damage.

Summary of design, usability, clean & general use

  • Slim and comfortable brush to hold
  • Minimalist design has perhaps gone too far
  • 5 cleaning modes
  • 1 brush head included
  • Alternative brush heads available
  • Built-in 30 second pacer and 2 minute timer tells you when to change quadrant and finish brushing
  • Automatically powers off at the end of cleaning cycle
  • Easy-start function
  • Great travel case, even if the connector is dated
  • Lacks a pressure sensor and Bluetooth
  • 2 year warranty as standard

Battery life

With any Sonicare by Philips product I have used, the battery life has always been really impressive.

In part, the battery technology used has a part to play.

The DiamondClean has a Lithium-Ion battery, the same sort that you have in your smartphone.  This type of battery lasts and performs better than older battery technology like Nickel Metal Hydride (NiMh).

This brush can last up to 3 weeks on a full charge and if you only use the ‘clean’ mode twice a day for 2 minutes.

The automatic power off facility helps conserve power, by turning the brush off at the end of each clean.

Some modes like deep clean last longer and thus consume more power and will reduce the usage time  At worst 2 weeks battery life is to be expected.  That is still a couple of days better than Oral-B brushes.

My testing confirmed the advertised 3 weeks cleaning time.  So that is some 84 minutes of cleaning time or 21 days based on 2 x 2 minute cleans each day.

Unless you are a frequent traveller, you will likely leave your brush at home.  It is quite safe to leave it on the charger at all times, but with such a long battery life you do not need to, you could pack it away.

Philips Sonicare DiamondClean Review 8

The charging stand it comes with is functional and could be taken with you when travelling as the 2 pin power connector supports 100-240v.

2 pin plugs are generally connected to the power supply found in a bathroom here in the UK.  Some homes (mine included) are not equipped with such.  It is possible to connect to a 3 pin socket by using an adapter.

That said, the travel case with USB charging is a more appropriate item to take most of the time.  With such great battery life you can even leave the power cable at home for the charging case on a two week holiday.

On the subject of the travel case, in the box is a USB cable and 2 pin USB plug that accepts the USB cable and in turn connects to the same 2 pin socket the conventional charging stand does.

I do not understand why on such a new brush the travel case still includes a MiniUSB connection rather than the more current MicroUSB or the really new and future proofed USB Type C connector.  I guess convenience on Philips part has a big part to play here.  It’s the same case as the 2nd gen model.

What this ultimately means is that when you travel you need to take another cable with you because the MicroUSB, USB Type-C or Lightning connector charger for your smartphone does not work.

Before first use you should charge the DiamondClean brush for 24 hours.  The charge indicator flashes green until fully charged. Rapid yellow flashing indicates that the battery is low and that you have fewer than 3 uses left.

After the first charge it does not have to be left on charge for as long, but leaving for 24 hours will ensure a full recharge of the battery.

Philips Sonicare DiamondClean Review 9

The DiamondClean model, unlike a lot of other Sonicare, Oral-B and Colgate models does away with a charging prong on the charging base.  Normally a prong on the charging stand would fit into a recess on the bottom of the brush handle and not only hold the brush upright but deliver the charge.

DiamondClean has used the same inductive charging process, but applied this to a flat surface.

With the 2nd generation, a charging glass was provided.  Designed to properly charge only one handle at a time, you could put the brush in the glass and it would lean within it.  It acted more like a traditional cup/holder you might put a manual toothbrush into when not in use.

This design made the holder a little better than the more conventional prong style design as if you knock the brush it would wobble in the glass and keep charging, whereas conventional chargers often sees the brush go toppling.

Therefore its slightly odd that this 3rd generation is a mix of the two.  No prong still but the glass has been replaced with plastic (to look like glass) and has been trimmed to an upright stand.

The charging base has a gloss chrome plastic to look like metal, then the clear plastic top (made to look like glass) sits on top of that.  The brush then sits in the recess in the clear plastic piece.

From a distance, it looks smart.  However, when you touch it the fit is not great and it feels much cheaper than all the other components. More practical and lighter, yes, but it is still prone to being knocked.  That said the brush holds fairly well within this stand. Just a bit of a shame really. The glass felt so premium on the second generation.

Summary of battery life

  • 84 minutes of usage time or 21 days usage based on 2 cleans a day
  • A charging stand is included in the box
  • Takes up to 24 hours to charge fully
  • The battery status light flashes green until fully charged
  • Works on 100-240 volts
  • Travel case lacks a current charging connection

Price & where to buy

I have included links to buying options here at the start of the review.

In the section below, I discuss the price more generally and in relation to similar products.

‘Not cheap’ is how I will start this section of the review, but, it could be a lot worse.

The recommended retail price of this brush is some £270, which is on par with the Oral-B Genius 9000.

Now, these prices are rarely upheld and probably some 99% of the time the prices are 50% or less lower.

This 3rd generation model cost us £121.50, that’s 55% less than the RRP.

At this sort of price, this brush is more reasonable, even if still £80 more than a more basic brush.

Whilst the brush is supported by a 2 year guarantee, here at Electric Teeth we work out the cost over a 3 year period as we believe from our research that this is roughly speaking the average time people will keep a brush for.  Keep it for longer and you get only better value.

You don’t need me to tell you that every 3 months you need to replace the brush heads, so over 3 years we need to factor in the cost of 12 brush heads.

Philips Sonicare DiamondClean Review 10

1 comes supplied in the box and the AdaptiveClean head is sold in packs of 4.

At £25 or thereabouts for a pack of 4, each brush head costs £6.25 each.

The cost of purchase of this brush becomes £190.50 (£121.50 + (11 x £6.25)).

Over 3 years this works out at a daily cost of 17p.

This price does exclude the cost of water, toothpaste and electric to charge it, but you get a rough idea.

You do have to consider that the most cost effective brushes work out at some 6-7p per day but do not offer the premium features.

There is a good chance the brush will last longer than the 3 year period and using the same brush handle but switching heads with other users in your household will only help bring the cost down and drive more value from it.

When it comes to making the purchase, if this is the bruh for you, be sure to shop around and pay the price you are comfortable with and from a retailer you trust.

Please note that all prices quoted are approximates and will vary based on location, supplier and time of purchase.  These figures were correct at the time of writing and should not be relied upon as hard fact, but used as a guide during your decision process.

Summary of price & where to buy

  • We’ve listed a live price comparison of UK retailers here
  • Recommended retail price of £270
  • Generally available for around £121.50, 55% off RRP
  • Brush heads typically available for £25 per pack of 4 or £6.25 each
  • Works out at around 17p per day over 3 years
  • Share brush handle with another user to extend value

Reliability & long term use

Here at Electric Teeth to test the electric toothbrush in a way that you would use it at home.

We have tested every toothbrush we write about. To date, we have not experienced any issues with the brush and see few real weaknesses

Only daily use for long periods of time will really tell how well a brush will stand up to repeated use and abuse.

The fact that Philips have been producing electric toothbrushes and other consumer products for so long means that on the whole they know what they are doing.

Philips Sonicare DiamondClean Review 11

Typically their brushes are really reliable and rarely will you have a problem.

If it does go wrong, it is backed by a 2 year warranty.

Lab tests or durability tests are not something we do and it is not possible to test every toothbrush day in day out and report back on how they fare.  However we take reliability seriously and always comment on where we think weaknesses are and should our opinion change as a result, we will issue an update to this review.

Do be aware that the Sonicare DiamondClean is water resistant so it can get wet and be wiped down with water but it is not waterproof so where possible avoid prolonged exposure to water to avoid doing damage.  Philips explicitly state in the user manual that it should not be used in the shower or bath.  Perhaps more caution than anything, but best not test it!


The DiamondClean electric toothbrush is overall a very good toothbrush.

If you are looking for a place to buy, we recommend checking it out here on Amazon.

It offers a lot and ultimately does a great job of cleaning your teeth.

The battery life is super, the build quality is equally as good and the very functional travel case is desirable as is the range of colours it can be purchased in.

Weaknesses explained in this review are primarily personal and you may feel different about them; but I do believe Philips missed an opportunity to make this brush that little bit better than they did, to really compete with the Genius 9000 from Oral-B.

That said, if I had to pick between the two, the decision would be tough.

I prefer the Oral-B for it’s features but I really admire the battery life and quieter motion of the Sonicare.

It does also have a 30 second pacer also referred to as a quadpacer.  At 30 second intervals a slight pause in the brushing mode to tell you to change quadrants.  There are 4 quadrants to the mouth.
  • How long does the battery last?
    • The battery lasts up to 84 minutes, which is equivalent to 3 weeks or 21 days of usage based on 2 x 2 minute cleans per day.
  • Does it come with a charger?
    • Yes, a charging station is included with the toothbrush along with a travel case which can also charge the brush.
  • The charger is 2 pin, how can I use it?
    • The charger is a 2 pin/prong charger designed to be used on voltages of 100-240 volts.  It is a 2 pin charger suitable for connecting to shaver sockets found in many bathrooms in the UK & Europe.  If you do not have a shaver socket, you can purchase an adapter that will allow the charger to be connected to a standard 3 pin UK mains socket.
  • Can this be fixed to a wall?
    • The charging station has not been designed to be fixed to a wall.
  • Can I use the Sonicare DiamondClean in the shower?
    • No, the manual specifically states not to use the DiamondClean in the shower or bath.
  • Does it come with a travel case?
    • Yes.  The DiamondClean comes with a hard travel case that holds the brush and up to 2 brush heads.

  1. Thanks for the review, it really helps to understand all the sonicare range of products.
    I cannot decide between the DiamondClean and DiamondClean 9000 that I can get for the same price.
    I am not interested in the Bluetooth capability, but I cannot figure out what and why they are different in terms of :
    Battery life (3 weeks vs 2 weeks)
    Cleaning modes
    Easy use with 2 buttons for power selection on Diamond series
    Pressure sensor only on 9000
    Which one is the most recent?
    Any suggestions on which one to go for?
    Many thanks

    • Hi Benoit.

      I personally would go for the newer DiamondClean 9000, even if you have no interest in Bluetooth connectivity.

      The key reasons for this is that some have experienced reliability issues with the original DiamondClean. Whilst never a 100 percent guarantee so far I have seen no complaints on the newer model with a slightly revised build/design.

      The newer 9000 has a pressure sensor and brush head replacement reminder built-in, which I think are useful.

      Truthfully this contradicts my comparison of these 2 models I have written here. But, at the time of writing there was quite a price difference.

      • Thank you very much for your swift response.
        This comparison is exactly what I was after and I could not find it before to write the previous message.
        Very insightful, as I could not find any proper comparison on Philips website or in my Fench native language.
        You mention in bold that the comparison is not conisdering the dual handled versions of the pack which I was actually looking at. Any reason for that or is it only from a package content perspective?

        • I am pleased it has helped.

          In comparisons, I simply try to keep it as fair as possible. Dual handle packages tend to be better value, but many are only looking for a single handled package. Therefore talking about the benefits of dual handled options confuses the comparisons and offers options that don’t suit or apply to the majority of readers.

          Ultimately trying to keep things simple. 👍

  2. I used the sonicare diamondclean with gum care head (g3) because of my gum recession and sensitive gums, but it didn’t clean perfectly my teeth: I felt dirty especially the inner faces from canine to canine. The shape of the head is quite rounded (the blue extreme tips are much higher while the white inner tips are lower) so the bristles are difficult to touch teeth and brush them. What went wrong in your opinion? Was it just poor technique or are the sonicare head really difficult in reaching some areas? Any suggestion?

    • Simone.

      Whilst any electric toothbrush is suitable for most people some will not get on with a particular model or brand for whatever reason.

      It can be the individual’s tooth and positioning, the size of the mouth etc. I wouldn’t necessarily say you were doing anything wrong. Maybe moving the brush head differently might have brought different results in your situation. Are you using the technique shown in this video?

      Maybe the small round brush head found on Oral-B toothbrushes might be better.

  3. Hi – is this classed as an ultrasonic toothbrush – if not what is the difference and what ultrasonic toothbrush would you recommend – thanks

    • This is not classed as an ultrasonic toothbrush Cathy, this is just a ‘sonic’ toothbrush.

      For it to be classified as ultrasonic, there would need to be more bristle movement.

      In terms of differences, rather that typing out a long(ish) comment, you should check out my article ‘Sonic vs Ultrasonic‘ that explains the differences.

      In truth I have not had extensive hands-on with ultrasonic models due to the limited range and demand, so to say which is ‘best’ would really be unfair at this stage. Going with a brand like Megasonex or Emmi-Dent should mean you get a quality product.

      The question is do you really need ultrasonic?

  4. Hi John,

    A quick review of Amazon negative feedback for the entire Sonicare range will reflect my wife and my experiences; our initial Sonicare toothbrushes lasted about 7 years (the one where you screwed on the head); when they finally died, we replaced them with expensive ‘push head’ brushes and the reliability of these is woeful. In the last 7 or 8 years we have had FOUR separate toothbrushes EACH and now these also need replacement- we’ve had the UV clean model (I forget the model number but had a little UV ‘cabinet’ to clean the brush head), two of the 2nd generation DiamonClean (each of us having one replaced under warranty), and we’ve EACH had two of third generation DiamonClean brushes (my wife the pink model, me the black model). The reliability is a joke – my second DiamonClean died a month ago and my wife’s has died this week.

    Quite telling is that neither Philips nor most resellers offer any optional extended warranty on this (Argos seem the exception and offer an extra year), and neither do Philips offer any out of warranty repair. These are essentially disposable items with a two year life span.

    I’m writing this here in the hope that others are made aware of what they’re getting into. The cleaning is superb and we will probably buy another, but I’d strongly advise anyone to spend no more than £50-£60 at time of purchase as you almost certainly will be buying another in 24-36 months

    • Hi Steve.

      Thanks for the detailed feedback.

      I know that the DiamondClean product has not been the most reliable of all the Sonicare models, but your situation is rather alarming for a number of reasons.

      Firstly, just the sheer number you have been though and secondly, the approach of Philips to just replace them, rather than repair.

      Of course Sonicare sell in big numbers so the number of complaints are likely to be higher, but this isn’t really an excuse.

      We aim in the future to do a bit more of an expose on product quality and dig further into repair and replacement processes.

      Generally we do recommend the ‘cheaper’ products as they are ideal for most people. Rarely does anyone need the more premium products.

      I am not sure what you have now opted for, but Oral-B do offer up to 3 year warranty on their brushes in the UK and you can get them repaired under warranty and when outside of the warranty period.

  5. Hi Jon,
    Thanks for great dose of knowledge!
    I wonder if I can use 2nd generation charger (glass) with 3rd gen toothbrush?
    Kind regards
