Smart pressure feedback helps you brush with just the right pressure. During brushing, the light ring gives you instant feedback on how much pressure you are using. It glows green when you're using the right amount of pressure, pulses purple with a gentle vibration if you're pressing too hard and slowly fades to purple when you're not applying enough pressure. As a result, you get the best cleaning results while protecting your teeth and gums. At the end of your session, the handle's display shows a mouth map highlighting where you may need to adjust pressure in the future.
After brushing, a glance at the handle's display will show you post-brushing feedback. The mouth map highlights any areas where you need to reduce pressure in the future. It provides you with personalised brushing guidance for ultimate care - all in the palm of your hand.

Very good
Honestly, this set is amazing. 2 toothbrush, perfect one for me and one for my husband. Firstly, I must appreciate the sleek design, especially the white one, they look so cool. I have been using it now for couple of weeks and my teeth have never felt cleaner. My gums looks lighter too and the plaque that was bothering me , now is almost gone. The teeth also look whiter. There are different settings, that are easy to follow and change as well. The battery life is absolutely amazing, it lasts 2 weeks for me , brushing twice a day.

Lovely clean, reaches hard to clean teeth at the back.
Pleasantly surprised by this product. The shape of the toothbrush head is narrower than other electric toothbrushes, meaning it gets to the backs of my mouth and wisdom teeth easier. Easy to charge with a stand that doesn’t leave mess on surfaces, compact and I like that there is an app that tells you how you’ve been brushing and when you’re due a new toothbrush head.

Very strong vibrantion and cleans brilliantly
This is the best toothbrush I ever used. Tge vibration is so strong, I felt like it was rattling my brain. Started woth low intensity and in few days got used to it and went to high intensity. My husband has few stains on teeth from smoking and we saw an improvement on them already. There are different settings like intensity, language setting and different modes (deep clean, gum care, whitening...). I really liked that it shows how many sessions left till you have to change the head. I also connected to an app, which is quite useful. It shows all your sessions, and pressure. You can also see if the pressure is ok woth the light kn the end of toothbrush. It came woth 2 chargers, one holder and one glass. I was surprised when I realised you can put the glass on the charger also. Me and my husband absolutely love these toothbrushes.
