Our Analysis and Test Results
While the Fairywill electric toothbrush has not received any updates since we last tested it, it has been renamed from the Fairywill Sonic to the Fairywill D7 Sonic. You can expect to pay a few dollars more and you'll now receive four brush heads instead of three. You can compare the two below: the old Fairywill we tested is on the left, while the new version is on the right.
We began our toothbrush testing regimen by rating and ranking how comfortable it is to use. We had multiple judges try out each brush and score the comfort level of each one, as well as measure how loud each brush is. We also checked to see if they have a pressure sensor to prevent over-brushing. The Fairywill fared quite well, earning an above-average score.
Our judges found the side-to-side brushing action of the Fairywill to be quite gentle. The bristles on the included brush head run just a bit stiffer than average, but we don't think they are too rough if you have gums on the more sensitive side.
We also like that the Fairywill isn't overly loud. You can hear it if you are standing close to someone brushing, but it is much quieter than many of the rotation-oscillation brushes out there. Unfortunately, this toothbrush doesn't have an indicator to alert you if you are brushing too hard.
Our next metric looked at how well the Fairywill did in our side-by-side cleaning test. We determined scores by having our judges use a plaque-disclosing tablet after refraining from brushing for around 18 hours, then using the Fairywill on its standard 2-minute cleaning cycles. We looked at before and after photos to compare how much plaque was removed. This electric toothbrush didn't deliver the best results but performed above average.
This toothbrush allowed our tester to easily remove the bulk of the plaque on the main surfaces of their teeth.
However, we did find that there were a few problem spots that it missed.
Ease of Use
Following cleaning and comfort, our next set of evaluations ranked and rated how easy each toothbrush is to use and how user-friendly the features and functions are. We looked at the ease of swapping the modes, how much of a hassle it is to clean the toothbrush itself, if there is storage for additional brush heads on the charging base, and if it has a two-minute timer — preferably with quadrant pacing. We found the Fairywill Sonic Toothbrush to be quite basic, lacking some of the convenience features of the top models, but its simplicity makes it very easy to operate. This earned it a score in the middle of the group.
The Fairywill has five different cleaning modes: white, clean, sensitive, polish, massage. You hit the power button to cycle through each mode, and there is an indicator light that shows you what mode you are in.
This toothbrush is rated for IPX7, meaning it's rated for accidental submersion to one meter but hasn't undergone any dust ingress protection rating. It's fairly easy to clean the bulk of the brush, but we did find some raised areas around the power button and a few seams that can accumulate toothpaste grime.
Unfortunately, the charging base for this brush doesn't have any spot for additional brush heads or include a travel case. This brush also has an integrated two-minute timer that notifies you when it's time to move to different parts of your mouth.
Our last series of tests evaluated and scored the battery life of each toothbrush. For this test, we ran it continuously (since it doesn't really have any standby power draw with its lack of smart features) and then figured out how many days it would have lasted for a single person with typical use. The Fairywill did exceptionally well in this metric, earning one of the best scores of the group.
We estimate that this brush would last for approximately 50 days, assuming you brush once in the morning and once in the evening — far outpacing most of the competition.
However, we did find it a little off that this model doesn't have an induction charger — like almost every other model — instead having a 3.5mm charging port at the base of the brush.
If you want to spend as little as possible on a new electric toothbrush and don't mind making some concessions, then the Fairywill is a solid value option.
There is no denying that the Fairywill is a relatively bare-bones and minimalistic electric toothbrush. It doesn't have a smartphone companion app or a ton of fancy modes, but we think it's hard to beat the price, and some people will probably prefer a toothbrush without all the bells and whistles that the top-tier items have. While this electric toothbrush might not be the best of the best, it does an acceptable job compared to the rest of the competition — and at a much lower price. It isn't without its flaws, but we do like how comfortable and easy to use it is.
