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.

Brilliant
I usually hate electric tooth brushes. I don't like the vibration because this could be turned down I don't actually mind it. It does a good job and I like the colour indicator on the bottle and the digital screen to tell you when it needs charging. Will have to see what the dentist says when I go for my next check up.

Feeling of very clean teeth !
I received this complementary product in exchange of my honest opinion . Since using it I feel like my teeth are cleaner . Between the 5 modes and 3 intensity there is choices ! The noise level is around the same as another electric . But it has a different type of vibration .

Amazing cleaning technology
Incredible cleaning power, absolutely love how interactive it is and how it perfectly selects modes and shows the time associated with your cleaning. It’s the best toothbrush I’ve ever used. I use on low power as I am just getting used to transitioning from a manual brush but this is great. Super lightweight too so easy to handle. Easy to assemble and so pleased I’ve made the move to an electric brush
