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.

The best toothbrush I've had!
Im very impressed with those toothbrush. I already had an electric toothbrush but its nothing compared to this. My teeth are noticeably cleaner and smoother after using the soft but firm brush. I like the different brushing modes and intensity settings so you can change it based on what my teeth need. The nose is light too especially on the lower intensity settings. Definitely not something to be concerned about. The battery life is excellent and lasts ages before needing to charge again and the charging glass is a cool feature too. The travel case is really handy as I go visit family a lot. Keeps it keep and tidy and clean while I travel! It is expensive and is probably worth it if you value the extra features its offers.

Highly recommended
I have been trying the philip sonicare Diamondclean 8500 and i am really impressed. It feels so sleek and premium, and after brushing my teeth feels really clean and smooth. I love how it is easy to use and the different brushing setting make it easy to choose what feels right for me.

Great sonicare toothbrush
What can I say about this toothbrush besides the fact that it’s amazing and it’s everything I was looking for! It looks very expensive and elegant, the black gives it even more elegance than other colours. I have been using this for a month and my teeth have never been cleaner. You can use what program you’d like from the 6 programs it has and it uses 3 intensities. My favourite thing is the smart pressure feedback, as it glows green for optimal pressure and purple if you press too hard. The battery holds more than 14 days, I don’t even remember when I charged it, plus if you’re travelling you can charge it via the case. It’s very comfortable to use, I’ve never had cleaner teeth and my gums are healthier. It also has an app which is very useful for a better brushing technique. Another thing that I like is the brush head replacement reminder. Everything about this toothbrush is amazing, I believe it’s worth the price.
