Pros and cons

According to our electric toothbrush expert

You can prevent tooth damage thanks to the pressure sensor, which gives a light signal when you brush too hard.
The toothbrush gives you a notification when the brush attachment needs to be replaced, so you can always replace it on time.
With 3 brushing modes, it’s harder to adjust the brushing intensity to your teeth and gums.

Our expert review

Polishes thoroughly with the right pressure

3 brushing modes
Smart brushing pressure sensor
Replacement bulb for brush attachment
No display

Thanks to the smart 3-color pressure sensor, I always brush with the right pressure and get good results. I can also easily choose a brushing mode that suits my teeth. The only thing is, the toothbrush doesn't have a display to show the brushing mode.

Different Brushing Modes I take the toothbrush out of the box, and the matte color immediately catches my eye. This gives the toothbrush a luxurious look and looks great in my bathroom. I can choose from 3 different brushing modes. I always use the standard brushing mode, which works well for my teeth. The toothbrush also has a sensitive brushing mode and a whitening mode. The sensitive mode brushes more gently and is good if you have sensitive teeth, for example. If I want to brush more thoroughly, the whitening mode comes in handy. The only thing is, the toothbrush doesn't have a display to show the battery life and brushing mode. So I have to judge which mode I'm using by the brushing speed.

Brushing with the right pressure I also like that the toothbrush has a handy pressure sensor. The light ring under the brush uses three colors to indicate whether I'm brushing with the right pressure. If I'm brushing too gently, the light ring turns white. The light ring turns red if I'm applying too much pressure. This protects my teeth from excessive pressure. When the pressure is correct, the light ring turns green. The toothbrush also has a built-in 2-minute timer. Every 30 seconds, the brush gives a signal with a vibration. The brush head needs replacing after an average of 3 months. Normally, I always had to keep track of when my brush needed replacing. This toothbrush keeps track of this. A yellow light on the toothbrush turns on when I need to replace the brush.

Accessories I notice that the toothbrush has a long battery life. I don't have to charge it often. When it's empty, I simply place it on the included charging station. This way, I can charge it effortlessly and it looks neat in my bathroom. The toothbrush also comes with a handy brush head holder. When I go away for a weekend, I put the brush head in the holder. This way, I can keep my toothbrush neat and hygienic in my bag.

Review is 6,0 out of 10.

cleans well, brushing modes very unclear...

does what it's supposed to do: cleaning
fits comfortably in the hand
has three brushing teeth, but no indicator which brushing mode you have...

Cleans well, but the brushing modes are a big mystery. You can switch between them, but you won't feel any difference and there is no indicator on the brush to tell you which setting you are in! Very inconvenient if you want to choose 'soft'/sensitive gums or 'extra white'. You have no idea what you clicked...

Review is 4,4 out of 10.

Battery delivered broken or much smaller than advertised

Battery lasts a maximum of 2-3 days

Works well, but the fact that the battery is empty after 2-3 days makes this electric toothbrush extremely annoying to use. Not 2 weeks, as advertised.
