October 2019: The FW-917 covered in this review, has been discontinued by Fairywill. The company still offer a range of great value toothbrushes. The FW-507 (view on Amazon) is the logical replacement within the Fairywill range. We do strongly advise considering the Sonicare ProtectiveClean 4100.
Please be aware this review looks at just one electric toothbrush from Fairywill.
They do have a number of other models, that offer different cleaning modes, features and box contents. At this time we have not completed separate reviews of these other models.
There are similarities across these models, but the naming convention for these brushes is complicated, to be sure to take care in picking the right one for you.
Whilst we have yet to review all the models independently, by reading this review you may pick up some information and insight that might apply to those other models and allow you to make a more informed purchasing decision.
You can view the Fairywill range here on Amazon.
If you are not bothered about the brand and want something cheap yet incredibly functional then the Fairywill FW-917 will serve you really well indeed.
As value for money goes the Fairywill have this pretty tied up. I can’t deny that you get a lot for your money.
- Slim and lightweight
- 3 cleaning modes
- Built-in timer and pacer
- Up to a month’s battery life
- Box contents is good
- Feels a little cheap
- As a new and unknown brand reliability and support concerns

The 3 BIG questions about the Fairywill FW-917
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-917. If I have missed something, let me know in the comments.
If you want more detail, you can read my full Fairywill FW-917 review further down the page, or watch my review video.
1. Is there anything drastically wrong with this toothbrush?
No, there is most certainly nothing drastically wrong with this brush at all, particularly when you consider the price. We currently rate it as the best budget electric toothbrush.
The biggest problem with this brush is the question of who are Fairywill?!
A Chinese firm they do not have the recognition of brands like Sonicare and Oral-B but if they continue to produce products like this then they should.
Refreshing as it is to see a new brand and contender within the electric toothbrush market, the resulting clean could be better, as could the length of the support.
We delve into these issues further in our Fairywill vs Sonicare & Oral-B post.
2. Which other brushes should I consider?
In many respects, there is little need to consider alternatives. The FW-917 Fairywill offers higher end features at a fantastic price.
3. Where is the best place to buy the Fairywill FW-917?
Amazon is the only retail outlet through which you can purchase this sonic electric toothbrush at the time of writing, but you can also check out eBay if you prefer that.
It is manufactured in China, but is available for dispatch within the USA.

And now for a bit more detail….
Fairywill are a Chinese manufacturer of electronic products or so it would seem from doing a bit of research on them.
They are not a brand I am familiar with and seem to be a new entrant to this space and have already made available a variety of different electric toothbrush models.
Quickly they have risen to be one of the most popular electric toothbrushes available from Amazon today, but whilst the features v the price is extremely favorable you have to consider whether this purchase is best for you.
Limited knowledge of the brand, supporting evidence on the performance of their brush and the post sale support come into question.

Pros & Cons
Here are what I consider to be the pros and cons of the Fairywill sonic toothbrush
- Design – Slim and lightweight
- Battery Life – Up to a months battery life – considerably more than the competition.
- 3 cleaning modes – Clean, soft and massage mode that can be selected before you begin the clean and have LED’s to show you which cleaning mode is in action.
- Box contents – Good box contents with additional brush heads
- Automatic power off – Turns off at the end of a cleaning cycle.
- Price – Cheap
- Quality – Product feels cheap in the hand and the finish whilst on the whole good, concerns about waterproof claims.
- Cleaning – The resulting clean may not be as good as other brands
- Reliability – A new brand with an unproven track record. 1 year warranty with CE, ROHS and FDA certifications that cannot be necessarily be confirmed.
Design, usability, clean & general use
Depending on your expectations for the price, initial impressions when you get the Fairywill sonic toothbrush in hand is pretty good.
For a start, the packaging is a lot smaller than many of the other brands with a good number of items included for the price.
The box is smart with a rundown of what’ is included and the brush features.
On this packaging are some claims which I can find no evidence to support.
According to the box, with the Fairywill can remove 100% more plaque within 1 week, improve gum health in just 2 weeks and achieve noticeably whiter teeth in just 2 weeks, when compared to a manual brush.
Super, all sounds good, if only it was clear how they have come to this conclusion. These are claims seen by other leading brands who have at least at some point conducted some clinical studies. With some digging you can find their supporting evidence, Fairywill lacks this.
I have no evidence to suggest so, but I have reservations about the use of the CE and ROHS safety labeling that appears on the box. It also appears on the manual, but there is no supporting documentation to say how they comply, etc. Sadly there is no way to check this easily.
They also show the FDA logo which is that of the US Food and Drug Administration. They have registered with the FDA here. I am unclear what checks have been performed into product safety etc and whether they can display such a logo on the box. To my knowledge, they have simply asserted their intention to sell this product within the USA.
Not shown on any of the promotional images on the outer box is the inclusion of an interdental brush head. This is a style of head that can be purchased separately.
This one head is individually boxed with the wording ‘To thank you for leaving your honest review’ on the box. Included as a sweetener to get a good review for the product it would seem.
In hand the brush feels ok, it looks quite smart. It is very plastic with polished silver plastic accents at the top of the brush handle and around the power and cleaning mode button.
Solid enough, it does not have the satisfying weight or build quality of an Oral-B model for example.
The body of the brush is primarily white in color.
On the front towards the top is a separate power and mode button that are a white rubber and surrounded by a silver piece of plastic.
Below the buttons is a panel containing the name of the 3 included cleaning modes with an LED above each. This LED shines blue when the brush is in use and the cleaning mode selected.
Within the same panel but towards the bottom is an LED for the battery power in the brush, it has the label ‘charge’ underneath it.
Outside of the panel, but below this charge indicator is the Fairywill logo.
Turn the brush around and the handle as a slightly squarer than rounded look to it. The sides are a gloss plastic whilst on the back are a series of grips at the top and bottom that the fingers catch on to hold the brush.
On the base is a recess into which the charging stand fits.
Inside the brush is the motor, the electronics, and the battery. This technology is during the manufacture pushed in from the bottom of the brush handle. There appears to be some gaps around the bottom edge. Whilst not overly concerned I am not sure how long term this will handle any water ingression.
The brush is said to be ‘waterproof’ but with an IPX7 rating it is a resistance rather than waterpoof. A rinse under the tap and maybe use in the shower is fine. Avoid complete immersion in water at all costs.
The brush head is detachable, but they do not just pull on or off.
You need to twist the brush head 45 degrees to the right (when looking at it) to unlock it. You can then pull it off and replace. Then turn the head 45 degrees to the left to lock it in place.
Each of the 3 brush heads included in the box has a detachable colored rubber band at the bottom that can be removed/replaced. These can also be used to differentiate between users.
Also included in the box is a small plastic cover that can be placed over the brush head when not in use/ it can kind of act like a travel cap.
The heads in the box are said to be medium/soft bristled and I would tend to agree. The bristles are colored and cut to varying lengths. The bristles do not appear to fade in color and as mentioned earlier I am not sure how tested the design of the bristles are.
Packs of replacement heads can be purchased for $8 for a pack of 4. (view on Amazon)
There is too the option to purchase a pack with hard bristles if that is your preference (view on Amazon). The recommendation is usually to go for the softer option.
Included was the interdental brush head which was a little strange and can be best described as a bristled head that has been shaped to a point. I found it a bit odd and can’t see it replacing my flossing routine or even the interdental brushes that I use. I get the principle of it though, some may like it.
A pack of 2 interdental heads (view on Amazon) will set you back $7, so they are a bit pricier than a standard head.
The psychical size of the Fairywill brush head is larger than that of Oral-B’s round heads but appears smaller than Sonicare’s larger brush heads. It should fit for most people to the hard to reach areas in the mouth.
The charging stand included is one of the smallest I have seen. I like the compact form factor. Built quality is just ok, it looks and feels a little cheap.
Unlike most other charging stands that have a molded power cable from the stand to the plug, this charging stand has a microUSB connector on the back of it.
It comes supplied with a separate USB to microUSB cable that can be connected to a computer’s USB port or a compatible mains charger you may have. It does not come with a power adapter.
Whilst this setup is not ideal for a bathroom, it is a convenient option for use internationally and gives more flexibility in the way in which you charge it. If your smartphone has a microUSB connector, you can use that to charge this brush.
The brush motor offers a sonic technology with a maximum 35,000 strokes per minute.
This maximum power and movement is felt on the Clean mode.
Soft mode has movements of 28,000 per minute, whilst Massage fluctuates between 28 and 35,000.
What this brush does do right is that you can select the cleaning mode prior to powering the brush on and you can see what mode you are using.
Even Oral-B brushes that retail for upwards of $80 do not offer this.
There is a 2 minute time and 30 second quadpacer built in but no pressure sensor.
A standard cleaning cycle lasts for 2 minutes as this is the recommended brushing time by dentists. You should do this twice a day.
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 at 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 section. 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. You can turn it on again if you like but this is a great feature that not only makes it clear that time is up on the clean, but conserves battery life too.
Brushing for the full 2 minutes is very important, but just as important if not more so is the right technique. Make sure you learn how to clean your teeth properly.
The brush is louder than a Sonicare brush, but quieter than an Oral-B in everyday use.
When it comes to the actual clean I have conducted no scientific tests. My mouth felt cleaner, as it should after the clean, but I did not feel as great about the cleanliness of my teeth as I do when using an Oral-B brush. Maybe the Oral-B is a bit harsher or creates a feeling of being better than it is, but I feel more refreshed after use with that.
This may also be partly backed by my concern of how engineered is the brush and the bristles. How good a clean do they really offer?
Boasting a months battery life, when the brush is low on power the charging indicator light will flash 10 times to remind you to charge. The amount of time it takes to charge the brush up completely might depend on how you are charging it, be that from mains power or a USB port on a computer. 15 hours should be more than enough time.
It is worth noting the brush is very light considering the length of usage time it offers. No mention of the battery technology, I surmise Lithium-ion.
I am more than happy for brands like Fairywill to come in an encroach on the market share that big brands occupy, I think there is the need for competition. However, some may struggle to have overall confidence in the product when things like the user manual is not written all that well.
It is readable and makes sense, but it is clearly not written by a native English speaker.
The 10 page manual covers the English, German, Spanish, French and Italian languages.
Not that you would expect it but the brush has no Bluetooth connectivity/smart features, a full sized travel case or any brush head storage is not included.
Summary of design, usability, clean & general use
- Slim and light to hold in hand.
- Looks ok but it is cheap to the touch
- 3 cleaning modes – Clean, Soft and Massage
- Can switch cleaning modes before switching the brush on
- Need to switch the brush on to change cleaning modes
- 3 brush heads included
- Free interdental brush head included.
- Built-in quad pacer and 2 minute timer tells you when to change quadrant
- Automatic power off at the end of a clean
- 30 day battery life, but no percentage indicator for clear feedback of remaining power
- Small charging stand, nice to power from MicroUSB
- Claimed waterproof but water resistant is more likely the case
- 1 year warranty
The box suggests 30 days battery life. I was skeptical given the weight and price of this brush.
It soon proved me wrong, it lasted for 30 days and then some.
Now whether I got lucky or not, but during my testing from full charge to flat, the brush managed 134 cleaning sessions.
That is 268 minutes of usage time. Simply incredible.
In truth that is 67 days of usage.
I would not suggest that all will last this long, I couldn’t quite believe it lasted as long as it did, but it clearly has the ability to last a month.
There is no information to say what capacity the battery is or what technology but it must be Lithium-ion.
To put this into perspective, the Genius Pro 8000 from Oral-B is one of the most popular brushes is about 7 times the price and its battery lasts. Its battery life is 48 minutes, which is equivalent to 12 days.
I was a bit concerned about the charging stand. It feels a little cheap and it and the brush get a little warm to the touch when charging, something I have not really experienced on other models.
Supplied with a microUSB to USB Type-A cable (normal full sized USB connector) this is not the normal charger you would expect with an electric toothbrush.
In some ways it is more convenient and versatile, accepting a connector like many popular smartphones, but it poses a potential safety risk for the bathroom or no way to charge it in a bathroom.
You need to connect the brush to a USB port on a computer, wall socket or compatible power adapter to charge it.
It is unclear exactly how long it takes to fully charge the battery, but I would suggest an overnight charge should be more than enough time.
When fully charged, the indicator light will turn off so you get some idea that it is charged.
It should apparently turn off to avoid overcharging too.
If the battery is low on the Fairywill the charge LED will flash 10 times to remind and alert you that it needs to be plugged in.
Summary of battery life
- Suggested 30 day battery life
- Achieved 67 days or 268 minutes of usage time
- Incredible performance given the weight of the brush
- Charging stand included
- USB cable provided to connect to charging stand.
- Charging light goes out when fully charged
- Light will flash 10 times when the battery is low
Price & where to buy
Just $19.99 is the cost of this Fairywill FW-917 as the time of writing.
For $20 can you really complain?!
This is a good price, no questions asked. Even if it did not offer the battery life and cleaning modes that it does.
Oral-B’s closest rival is around $40, offers a fraction of the battery life and 2 less cleaning modes.
The brush heads for this model are available in packs of 4, retailing at $8. This makes them just $2 each.
Some might say this is a little expensive given the cost of the brush itself, a new head is 10% of the purchase price. But, you do get 3 brush heads in the box, where typically you would get one so there are some cost savings here.
If you have seen any of our reviews here at Electric Teeth, we like you work out the cost of the brush over a 3 year period, which we see to be the typical ownership period.
Using the average cost (based on one user) and ownership over 3 years the Fairywill will cost $36 or $0.03 cents per day to own.
This price does exclude the cost of water, toothpaste and electric to charge it. This price also works on some assumptions, but you get a rough idea.
This is by far one of the cheapest electric toothbrushes to date. However, when you consider my comments regarding potential reliability, it may be worth pricing this brush over a shorter time period. Even then, it does still come out as an excellent value option.
You can bring the cost down further if you were to share it with other members of your household. All you need invest in is extra brush heads.
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
- Purchase price of just $19.99
- Available from Amazon, or can be found on eBay
- Works out at around $0.03 cents per day over 3 years
- Share brush handle with another user to extend value
Reliability & long term use
Unlike the Sonicare and Oral-B brands where there is a history of products and reliability, we have nothing to go on here.
We have and know of Oral-B and Sonicare brushes that are still working 5-10 years later.
My initial feelings are the Fairywill will not fare so well.
For a start, it comes with a 1 year warranty compared to the 2 year offered by the other brands.
I have not tested their warranty process or seen comment on any failings in it as yet, but past experiences make me question just what that will be. I suspect if you were to suggest the brush was faulty, they would send you a new one rather than repair.
Whilst the build of the brush is strong enough, it feels cheap and does not give the same confidence in hand as major brands.
My biggest concern is the sealing, particularly around the base of the brush, there are obvious gaps, I am assured however this is normal, fine and the brush is still water resistant.
Claimed to be waterproof, the product is most likely water resistant as the manual says do not soak the product in water for a long timer.
During my testing, the brush continued to work but this is one of the first brushes that I can’t confidently say will stand the test of time.
Unlike the 2 year warranties offered by the big brands, Fairywill offer just 1 year.
If you are not bothered about the brand and want something cheap yet incredibly functional then the Fairywill FW-917 will serve you really well indeed.
As value for money goes the Fairywill have this pretty tied up. I can’t deny that you get a lot for your money. They also have some nice touches which the big players should really consider ensuring are in more of their brushes.
However, whilst value for money is one thing, ongoing reliability, and peace of mind are another.
For me, I recommend this brush with caution. Personally I would be very tempted to spend a little more to get a more tried and tested brand and model, Such as the Sonicare ProtectiveClean 4100, but with the better models being at least double the price, you and I can afford for 1 to fail.
