Fairywill FW-507 / D7 Review

Fairywill FW-507

We have recently stopped recommending Fairywill as the budget choice in our best electric toothbrush post. 

At present we do not recommend opting for Fairywill as a cheap alternative to products from better known brands.

This is due to direct reports we have received about the rate at which Fairywill products fail. 

Further to this point, Fairywill products were removed from Amazon due to the company abusing the review system.

They were found to be offering free products in exchange for positive reviews, and offering replacements of broken products in exchange for positive reviews. 

We have a news post here that covered this event when it first happened.

Fairywill products come with a 1 year warranty, which is less than the 2 years offered by leading brands such as Oral-B. 

In our testing Fairywill products worked well for the period during which we tested them. However, we are unable to test all brushes for a long period of time, and the reports we have received suggest products have a good chance of failing within 6 to 12 months. 

Should the situation around the reliability of Fairywill’s products change, we will reconsider this advice. 

Our Verdict

The materials and overall finish make it look and feel a little ‘cheap’ in comparison to those brushes made by arguably more reputable and household name brands.

However, the low price is what really makes this toothbrush stand out.

This is without a doubt excellent value for money.  You will be hard pushed to get more features and performance for less.

The 3 BIG questions about the Fairywill FW-507

If you are short of time, the answers to the following 3 questions should let you know all you need to about the Fairywill FW-507 electric travel toothbrush set.  If I have missed something, let me know in the comments.

If you want more detail, you can read my full FW-507 Fairywill review further down the page

1. Is there anything drastically wrong with this toothbrush?

No, there is nothing drastically wrong with this toothbrush.

2. Which other brushes should I consider?

The answer to this question depends a little on what is most important to you.  

Is it value for money or having multiple features built-in?

I am going to presume value for money, as this is more often the case.

This, therefore, leaves me to suggest the Philips Sonicare 4100 Series as the ‘best’ alternative but you may also wish to consider the Oral-B Smart 1500.

The Sonicare offers the most similar brushing style, with a sonic cleaning action. It feels solid and premium in hand too.

Like the 4100, the Oral-B 1500’s battery life and features are inferior. But the small round brush head cleans the teeth really well.  It is also easy to grip onto.

If you need further direction our guide to the best electric toothbrushes will surely help you.

3. Where is the best place to buy the Fairywill travel toothbrush set?

As per our note at the top of this article, Fairywill products are no longer available on Amazon.

Fairywill is now selling products via its own online store.

Video Review

Fairywill FW-507 Review [USA]

And now for a bit more detail…

Fairywill is a Chinese manufacturer of electronic products, primarily electronic toothbrushes.

Just a few years ago they were a new and unknown brand. 

Today, they are still unknown in the grand scheme of national and global brands, but they have managed to carve out quite a reputation in the market of electric toothbrushes.

They have achieved this by offering extremely good value for money products, backed up with good service and support.

Variants of this toothbrush

At the time of review, there are what I would class as 4 different variants of the 507 electric toothbrush from Fairywill.

Whilst 1 version might well be simplest for all concerned, these variants are far less confusing than some other brands.

The features and technical ability are the same with all variants, what differs is the box contents and price.

To start with the base model of the FW-507 comes in 2 colors:

  • Black
  • White

These come with:

  • 1 x brush handle
  • 3 x standard brush heads (color matched)
  • 1 x interdental brush head (color matched)
  • 1 x charging cable
  • Documentation
Fairywill FW-507 / D7 Review 1

The next variant, known as FW-507Black+420 has the same box contents as listed above, but also comes with a travel case to hold the brush handle and 1 brush head too.  The handle is available only in black.

The fourth variant is the FW-507+420+8.

This comes with the same box contents as above but has a travel case and an additional 4 standard brush heads (7 in total (8 if you include the interdental head)).  The brush handle is black in color.

Although I refer to the FW-507 throughout it is the more premium FW-507+420+8 variant that I am reviewing here and that you see in the hands-on photos.

This model represents the best value for money.

The entry level FW-507 is often about $5-10 cheaper, but this saving is outweighed by the extra brush heads and travel case included in the box.

What’s in the box?

  • 1 x Fairywill FW-507 brush handle
  • 7 x standard brush heads (colour matched)
  • 1 x interdental brush head (colour matched)
  • 1 x travel case
  • 1 x charging cable
  • Documentation
Fairywill FW-507 / D7 Review 2

Key Features

  • 5 cleaning modes
  • Built-in timer and pacer
  • 30 day battery life
  • Up to 40,000 brush strokes per minute
  • Travel case

Pro & Cons

Here are what I consider to be the pros and cons of the Fairywill FW-507.

The Positives

  • Lightweight – The lack of weight makes it easy to hold and move about, and a pleasure to use.
  • 5 cleaning modes – Although not all are necessary, the ability to select lower powered, more gentle modes can be a benefit for those who are new to electric toothbrushes or suffer from sensitive teeth and gums.
  • Built-in timer and pacer – Helps you brush for the dentist recommended amount of time.
  • Battery life – With a minimum of 30 days battery power between charges, this outperforms a lot of the competition.
  • Box contents – You get all you need in the box, including a travel case.
  • Price – Excellent value for money.
  • American Dental Association approved – The brush has undergone testing and approval from one of the leading bodies in dental care within the USA to achieve its seal of acceptance.

The Negatives

  • No pressure sensor – There is no sensor to alert you if you are brushing too hard.
  • Charging port – Located on the bottom of the brush handle, it is not the most convenient location and may become damaged by water.
  • Quality – The plastic construction is functional, but not the premium fit and finish of some other products.
  • Lesser known brand – Reputable, but do not have the recognition and clinical backing like major brands do.

Design, usability, clean & general use

The FW-507 comes in a fairly simple cardboard box.  It doesn’t scream look at me and it is not as bulky as some toothbrush boxes.  It serves the purpose with key details/features being highlighted.

Pull off the outer cardboard sleeve to reveal a cardboard tray with a plastic tray positioned inside.  Within this sits the travel case, 2 standard brush heads and the interdental brush.

Inside the case is the brush handle and a further brush head, with the remaining brush heads, charging cable and documentation being stored under the plastic tray.

The handle and each individual brush head are wrapped in plastic.

Fairywill FW-507 Box

The first thing you notice about the FW-507 when you place it in the hand is how light it is.  Most of the weight is at the bottom of the handle, which clearly helps keep it balanced when it is stood upright.

As I have mentioned, the brush does come in black or white, but in this bundle variant black only.

It looks smart in black and the brush heads are color matched.

Made primarily of plastic, whilst the handle feels robust and good enough, it does not have that premium in hand feel that you get with Sonicare.

It is unfair to say it feels cheap, but it doesn’t evoke the same feel or premium you get with some other products.

The plastic has a matt coating to it, so it is not glossy or slippy which is good, because there is a distinct lack of raised gripping points or rubber grips to give that extra reassurance in the hand.

I should note that the majority of brush heads do have a more glossy finish to the plastic in comparison to the handle.  That said, a few of the heads did have a matt finish.

Fairywill electric toothbrush FW-507

On the front of the toothbrush handle, at the top, is the Fairywill logo.  This is white in color.

Beneath this is the power button, that turns the brush on and off and allows you to select the cleaning modes.  

It has a power icon debossed into it and is surrounded by a copper/rose gold colored ring which naturally draws the eye to the button.  The button itself is plastic and not finished with silicone or rubber from what I can tell.

The button’s feedback is adequate, not too clicky, not too resistive.

FW-507 toothbrush handle from Fairywill

Running down the majority of the brush handle is a rounded rectangle panel that has a number of icons within it.  5 are the cleaning modes and the 6th an icon for charging.

Each icon looks white in color and has text beneath it.

The order is as follows:

  • White
  • Clean
  • Sensitive
  • Polish
  • Massage
  • Charge

There is a larger gap between the massage and the charge icon, just to make clear they are essentially separate.

Fairywill FW-507 toothbrush handle

All the cleaning mode icons are backlit, being lit blue when selected.

The charging icon does not light up blue, it lights up or flashes red subject to its status.  More on that in the battery life section of the review.

The sides and back of the brush are smooth and free of any notable detail.

On the base of the brush, in the center is where you find the 3.5mm charging port, into which you connect the provided USB charging cable.  There is too a bit of regulatory information printed here.

Fairywill USB charging cable and power port

The battery and electronics are not designed to be removable.  Fairywill suggests the toothbrush is waterproof for the shower and bath, but do say avoid soaking in water.

If the brush head is not attached, you will see, extending from the top of the brush is a white plastic shaft.  This feeds into the motor and electronics sealed inside the handle.

The brush head connects to this.

To connect the brush heads, you slide them over the white plastic shaft at the top of the handle.  

Place each head so that it is turned about 45 degrees off center, to the right (if looking head on). Then once pushed as far down as it will go, twist the head from right to left by about 45 degrees to lock it into place.

Reverse this process to remove it.

Unlike Sonicare and Oral-B toothbrushes where the heads push straight on and off, with Fairywill there is this small locking mechanism that requires the head to be turned.

Fairywill FW-507 / D7 Review 3

As I have mentioned, you get 7 brush heads included in the box.  6 of these are what Fairywill calls ‘soft bristle’ brush heads. They also include 1 ‘hard bristle’ brush head.  

To me, the ‘soft bristle’ heads feel a little firmer than the soft brush heads from Oral-B and Sonicare, but they are certainly not the firmest brush heads I have used.  You can tell the difference between the soft and hard Fairywill supply.

Both bristle styles can be purchased in packs of 4 as spares/replacements.

The bristles on the head are cut in such a way that the head has a ‘w’ profile to it when looked at side on. 

Although the bristles are in an array of colors (blues and greens), none of them fade over time to act as a reminder to replace your brush heads, which is a shame.

Fairywill FW-507 toothbrush heads

You should replace the heads every 3 months on average, sooner if they are showing obvious signs of wear.

With 7 heads in the box, you don’t need to worry about purchasing replacements any time soon.

The provided interdental head might be useful for some.  It wasn’t ideally suited for me and my interdental spaces.

What is essentially a small tuft at the top of the head, it helps clean in the gaps between the teeth.  I personally think true interdental brushes or floss are better at cleaning these gaps, but the convenience of this might be something you like.

Just like the standard brush heads, you can buy spares/replacements of these also.

The FW-507 has a sonic motor built-in which means the way in which it cleans the teeth is the same as a Sonicare toothbrush and it does not offer an oscillating-rotating action like Oral-B toothbrushes.

The motor offers up to 40,000 brush strokes per minute, which is a lot.  Sonicare toothbrushes offer up to 31,000 brush strokes.

Don’t worry too much about the number of strokes, it really won’t make that much difference to the overall cleaning capability.

Fairywill FW-507 / D7 Review 4

Whilst I cannot say precisely how many strokes the motor generates for every mode, you can certainly tell that each of the 5 modes are programmed differently, using more or less power of the motor to offer a different cleaning experience. 

White is clearly the most powerful and sensitive the most gentle.

The overall cleaning performance of the FW-507 is more than satisfactory, but I never got the same just cleaned feeling as I do with Oral-B and Sonicare.

Despite the brush motor offering more strokes per minute, the resulting clean just didn’t feel quite as satisfying.  It is hard to explain. It does the job, but to me, the leading brands offer an extra sort of ‘pop/wow’ to the clean that make me feel I have done a great job of cleaning the teeth.

The FW-507 has 5 brushing modes as I mentioned previously.

To reconfirm they are:

  • White
  • Clean
  • Sensitive
  • Polish
  • Massage

You do not need 5 modes on a toothbrush and there is limited evidence to really suggest any of the modes actually do or achieve different results.

That said, I do think the Sensitive mode is the best alternative to a regular clean mode, as this generally uses less power and is a more gentle clean, should you require it.

Fairyiwll toothbrush cleaning modes

In fact, first-time electric toothbrush users might want to start with this mode and move to the regular clean mode after a couple of weeks, once you have gotten used to the extra power compared to a manual brush.

Unlike some toothbrushes that have a separate power and cleaning mode button, the 507 has just one button to turn the brush on and control the modes.

Press the power button once to turn it on, then press it again to begin to cycle through the modes.  Keep pressing it until the mode you want is selected. When selected, the icon on the handle will be lit with a blue light.

If you have selected massage, the last mode on the brush, another press of the power button will turn it off.

Fairywill FW-507 / D7 Review 5

You can press and hold the power button at any time to turn the brush off.

The brush will default to the mode you last used, which is handy and saves you having to cycle through the modes each time.

Each cleaning mode lasts for 2 minutes and will at the end of the 2 minute clean turn the toothbrush off.

If you want to brush for longer, you will need to turn the brush back on again.

On some Sonicare and Oral-B brushes, certain modes will last for longer than the ‘normal’ 2 minutes.  This is not the case here.

2 minutes is the dentist recommended minimum time you should spend brushing your teeth, hence the modes lasting this long.

Associated with this, is the built-in timer and pacer, which is activated by default on any mode.

During the 2 minute cleaning cycle, a timer in the brush keeps track of what is going on.  At 30 second intervals, the brush will provide an audible and psychical warning via a slight pause in the brush motor to tell you to change quadrant. This is your built-in pacer.

Imagine your mouth broken up into 4 sections. Upper right, upper left, lower right and lower left.  

You should spend 30 seconds cleaning each quarter in your mouth.  The pacer helps you keep an even brushing time on these 4 sections.

At the end of the 2 minutes, the brush automatically powers off, that is your clear sign that you have completed the required brushing session.

Fairywill FW-507 / D7 Review 6

The Philips Sonicare ProtectiveClean is a good alternative brush to consider alongside the Fairywill.  What this has, that the Fairywill does not, is a pressure sensor.

Brushing the teeth with too much force, i.e. scrubbing them is bad.  Many do not know that they brush with excessive pressure and it is the pressure sensor that alerts them to this, reducing the chance of damage being done to the teeth and gums.

Although the 507 lacks this feature, you just need to remember that the bristles need really only skim the surfaces of the teeth, you don’t need to brush hard to clean the teeth well.

Included in the box is a travel case which in my opinion is a great addition and really useful.  You don’t need to be a frequent traveler to get benefit from this. Even if you are only going away for 1 or 2 nights, it can be good to know that your brush is protected from damage or accidental activation as you pop it in a bag.

It is a hard plastic case, which is hinged on the right hand edge. 2 magnets secure the case closed rather than some sort of potentially clunky clip mechanism.  

The base of the case is a gloss black plastic, whilst the top is black in color but textured. The inner plastic lining is white.

FW-507 Fairywill travel case

Inside the case is space for the brush handle without the head attached and then a space for the brush head.

Often travel cases have a space for an additional head, but this is not the case here.

There are no vents in the body of the case for air to flow through, which is a bit of a shame, but not a make or break issue.

It is a touch thicker at the bottom of the case compared to the top.  I do feel like the whole thing has been designed to be as slim as it can whilst offering some protection.

Just to be clear, you cannot recharge the toothbrush in the case.

Fairywill is a lesser-known brand, so you don’t get some of the reputation benefits with this as you do Oral-B, Sonicare and Colgate.  

But countering that somewhat are the cost savings, and features you get for the price.

As I touch on later in the reliability section, it does come with a warranty, which is stated as 1 years. Register online and you can extend this by 6 months.

To my knowledge should issues arise they are very prompt to sort them out, usually sending a replacement product.

And the fact that the FW-507 has been granted their Seal of Acceptance from the American Dental Association (ADA). This means it has undergone testing and approval by a body of professionals to be awarded such, giving you the confidence of knowing that this is a product that performs.

Summary of design, usability, clean & general use

  • Lightweight functional handle
  • Matt finish plastic
  • Lacks a few gripping points
  • 5 brushing modes
  • Up to 40,000 brush strokes per minute
  • The cleaning action is satisfactory but doesn’t give the same intense clean as some other brushes
  • A single power button also controls the cleaning modes
  • Automatic power off
  • Built-in 2 minute timer and 30 second pacer
  • No pressure sensor built-in
  • Charging port located on the base of the brush handle
  • Travel case provided to hold 1 brush head and the brush handle
  • American Dental Association approved

Battery life

There is differing opinion on the importance of battery life.

Some users like a toothbrush to have a long battery life, so it can operate for longer between charges. Others are happy with relatively short battery life, as a toothbrush often sits on the charging stand when not in use anyhow.

Personally, I am somewhere in the middle.  I don’t want to have to be constantly thinking the toothbrush needs charging, but I don’t need it to last for months on end.

I think that to satisfy most users a minimum battery life of 2 weeks is a fair request of manufacturers.  I think this covers the majority of people who may travel frequently for work, go away on vacation, etc. For me, I don’t want to have to take my toothbrush charging stand when going away on a 2 week vacation.

Fairywill FW-507 / D7 Review 7

The good news is that Fairywill have you covered here and they claim a minimum battery life of 30 days (1 month) on a single charge.

30 days of battery life is very impressive.  Most Oral-B toothbrushes are around 1-2 weeks and Sonicare tends to be 2-5 weeks.

Having previously used other Fairywill toothbrushes, I have high expectations of the battery.  When I tested the FW-917, it lasted for a total of 2 months on a single charge, which is quite incredible.

So, the FW-507’s built-in lithium-ion battery should, according to the manufacturer, last a minimum of 60 brushing sessions, each 2 minutes long.  That is a total running time of 120 minutes.

In my hands-on testing, from a full charge through to going completely flat the brush achieved 130 brushing sessions which is equivalent to 260 minutes of running time or 65 days of use.  This is really impressive.

Unlike many toothbrushes that come with a charging stand, the 507 does not.  Instead, it comes with a USB to 3.5mm cable that you connect to the brush to charge it.

Fairywill USB charging cable

This is both a positive and a negative.

The positive is that the slim cable is small and lightweight and can be easily taken with you, should you be on an extended trip and need to recharge the toothbrush.  It is not bulky like a charging stand. It also allows the brush to be charged from USB ports on a computer/laptop or even a portable battery pack if required.

The negative to only being a USB to 3.5mm cable is that the cable is fairly easy to mislay or lose.  

Although Fairywill does sell replacement cables, it is perhaps a little more difficult to purchase a replacement than it might be for a Sonicare or Oral-B toothbrush. 

To charge the brush in the bathroom you will need a USB power adapter (much like you get with your smartphone) to connect the USB cable into and power from the wall socket.

Some users like the toothbrush to have a home in their bathroom and the charging stand that is usually provided is a convenient option.  You do not have this choice with the FW-507. It could be placed in the travel case, it could just stand on the countertop or be placed in some other storage holder if required.

Fairywill FW-507 / D7 Review 8

The last negative with this approach to charging is the position of the power/charge port on the FW-507.  It is on the base of the brush. This potentially poses a couple of issues. You can’t keep the brush in an upright position when on charge because of the way the cable connects.  This means you will likely want to remove the brush head, to stop the bristles making contact with other things or possible dirt that might exist on the surface that you are placing your toothbrush on to charge.

The port on the base of the brush is very fractionally recessed, but I worry that over time water and moisture could get into the charging port causing some form of damage.  Whilst few would intentionally sit the brush in a small puddle of water it can happen and moisture can get into that port, albeit not easily. This said, Fairywill says the toothbrush is waterproof, so I trust they have recognized this potential issue.

I should mention, that the case that comes with the toothbrush does not have any charging mechanism and cannot be powered or recharged through the travel case itself like the Philips Sonicare DiamondClean Smart can.

On the brush handle is a ‘charge’ icon.  It looks like a 2 pin plug.

This icon lights up to give you information on the status of the battery.

When the power in the brush is low, the light will flash red 10 times to remind/alert you to charge it.

The light will turn a steady red color when connected to power and charging.

When fully charged, the light will turn off to signal it is full and will shut off the charging mechanism to avoid overcharging.  The brush should fully charge in about 4 hours.

Summary of battery life

  • Claimed 30 days of battery life
  • Achieved 65 days on a single charge – equivalent to 130 brushing sessions
  • The battery is built-in and not user replaceable
  • Lithium-ion battery technology
  • USB to 3.5mm cable provided for charging
  • Charging port on the base of the toothbrush
  • ‘Charge’ icon on the front of the brush handle
  • The charging icon flashes red 10 times when the battery is low
  • The charging icon stays a steady red when on charge
  • The light on the charging icon turns off when the battery is fully charged

Price & where to buy

The Fairywill D7 / FW-507 is available here via Fairywill’s online store. You can get a 15% discount using the code ELECTRICTEETH (if there are no other offers running).

One of, if not the primary approaches Fairywill have taken to carving out a bit of market share for themselves is through the distribution methods they use and the prices that they charge for their products.

Where large brands often have a high recommended retail price, but an average selling price of around 20% less, that is not the case here.

Fairywill FW-507 / D7 Review 9

The suggested retail price of the Fairywill FW-507 bundle option I am reviewing is $35.

For the most part, this is the price at which it sells too. Occasionally it dips down a few dollars.

For this price, you are getting the brush handle, 7 brush heads, and a travel case.  No major brand even comes close to this.

I am not lying when I say that a pack of 4 Sonicare toothbrush heads alone can cost more than this toothbrush! (I am talking about the premium heads sold at full retail prices).

If I based a comparison on box contents and features alone you would be looking at $100+ or more to get the equivalent from Oral-B or Sonicare.

What is the cost of the lower price here? Quality? Reliability? Design? Maybe, it is, of course, personal and subjective.

Here at Electric Teeth, we like to calculate the cost of ownership over a 3 year period, to give some sort of benchmark as to how much a brush costs to own.

Over 3 years, on average you need 12 brush heads.  The FW-507 comes with 7 of those included, so another 5 would need to be purchased.

Available in packs of 4, they sell on average for $10 per pack, so $2.50 per head.

Fairywill FW-507 / D7 Review 10

This means, we have $12.50 of brush head costs to add to the $35.  A total of $47.50.

This gives a daily price of 4 cents.  

That is staggeringly cost effective.

As important as price is, this is only part of the overall considerations you should make.  So unless you are restricted, you should still consider the other options.

The Oral-B Smart 1500 might not offer as many cleaning modes, nor might it have the same battery life.  But, it does feel like it cleans the teeth better and is made by a more recognized brand. This works out at 11 cents per day.  

As for a Sonicare made alternative, the suggested 4100 works out at around 14 cents per day.

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

  • Very cost effective
  • Retail price of $35 and tends only to drop by a couple of dollars
  • 7 brush heads and a travel case included
  • Replacement brush heads are $10 per pack, $2.50 each
  • $47.50 to own over 3 years, just 4 cents per day

Reliability & long term use

Over the last few years, Fairywill have begun to build a fairly good reputation for service and support.

Whilst I have not had one of their products fail on me, I have learned that in most instances, providing it is within the warranty period, a new replacement will be sent out.

Not always will this be the case, but returning the faulty product is not normally required either, saving expense and hassle.

Larger household brands like Sonicare, Colgate and Oral-B have more established networks and reports on their reliability, but they are not free of complaints.  

Fairywill FW-507 / D7 Review 11

Fairywill does offer a 1 year warranty compared to the 2 year which is typical with most other brands. 

Register online and you can extend this by 6 months. Another years warranty would be preferred, but are the cost savings worth it?! Quite possibly.

As the products are sold through Amazon, you can use their returns procedure if eligible or you can contact [email protected] for assistance.

Although the FW-507 is made from cost effective plastic materials, I can’t honestly say it will fail sooner than the more durable feeling alternatives. The brush appears solid, with no obvious breaks in the plastic body or weak looking seals.

The biggest weakness, in my opinion, is the position of the charging port on the base of the brush.  Whilst most won’t actively have the brush sit in water, there is a potential that the base may sit in a small pool of water and over time, this could ingress to and damage the charging port.

Hopefully, this won’t be the case.  I haven’t found any complaints that confirm this has happened, but the potential does exist.


This Fairywill electric toothbrush is not perfect, but then again I don’t think anything is.  

Even if I did, your opinion may well be different.

What I think most can agree on, is that when you take into account everything that you get within this bundle, it is very difficult to complain about it.  The value is simply superb.

The whole package is well thought out and gives new and experienced electric toothbrush users something to be happy about. From the impressive battery life, provided travel case to the built-in timer and pacer.

Without a doubt, opting for a big brand toothbrush does, psychologically at least, give an extra bit of peace of mind due to the added scrutiny these products come under, but as the saying goes, you get a lot of bang for your buck.

8 thoughts on “Fairywill FW-507 / D7 Review”

  1. bought the D7 on Ebay from welplus on Feb 21 went well for about 8 months then stopped working even when fully charged tried contacting seller with several emails through ebay but no replies now out of warranty and left with unusable heads

  2. I recently purchased online approximately 6 months ago and it quit working already. Quite disappointing I did enjoy it while it worked.

  3. I have the Fairywell 507. I bought it through Amazon. I
    am very satisfied with it’s performance so far. After I
    finish brushing I rinse my mouth and then rub my finger over my teeth. They squeak when I do this. That
    has always been my way of telling me that I’ve done
    a good job. Having a 507 puts a smile on face…

  4. Yours, in my opinion, is an exemplary piece of review writing–clearly written, informative, and comprehensive in coverage. Thank-you!

    Fairywill evidently is leveraging their price-to-value advantage relative to the other Name brands in the sonic toothbrush arena (–bizarre concept, “toothbrush arena!”)

    I recently bought their FW-917 toothbrush in an Amazon “lightning deal.” It came with its USB charging cable and 3 soft brushes plus a fourth inter-dental brush, but no travel case, for under $24 including sales tax with the deal’s 15% price reduction.

    At that price point, I’m happy to experiment with trying a sonic electric toothbrush for awhile in lieu of using a manual one, and if it doesn’t work out, I’ll be at a pretty minimal loss compared to having bought one of the other brands. But I’ll add that, so far, I’m liking using this sonic brush quite a bit.

    Here’s a last bit of supplementary info, for what it’s worth: I believe the product warranty can be extended for free by an additional 6 months to 1-1/2 years total if one registers post-purchase as a “VIP” member via their FaceBook page.
