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.

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.

Squeaky clean teeth
This is my first Phillips toothbrush to try. I will get straight to the points. I gave it a good 4 weeks trial before reviewing. Brush head. Bigger head and covers more area, making it easier and faster to clean. The handle. Has got a digital screen. Swipe with your thumb to get to the needed settings, press the middle button to pick the settings. Other Accessories. My set included a charging lead, a charging base, a glass, travel case and the toothbrush. No extra brush heads. Settings. There are few modes to choose: clean, deep clean, white, gum health, sensitive and max care. And each mode has 3 settings for brush strength: low, medium & high. The bottom part has the light that gets green for good pressure and purple for not enough or too much pressure. Which actually made the process fun. You can also see the feedback with the map of your mouth showing which areas need more/less pressure. Charging. Took quite a long time to fully charge first time. But once charged you get the display showing you have 178 sessions (89 days if you clean twice) and the percentage of the battery left. Each cleaning session lasts 2,4 minutes. Which is not entirely true, I had 90% charge remaining after 1 week of use and less than 50% after 1 month of usage. But still this is impressive. You can always keep the brush charging in the glass, I just wanted to test how long it would last without the charger. Overall impressions. This definitely made the whole morning routine more fun. But the most important thing I have noticed, after only 1 week of using it my gums stopped bleeding completely. I had this problem with all my previous toothbrushes, no matter how thoroughly I cleaned my teeth the occasional bleeding was there and the hygienist said it is because of buildup bacterias. And because it cleans so well my breath stays fresh till my next meal. Will I recommend it? Absolutely! Worth every penny!

Teeth feels so clean and smooth
This philips diamondclean electric toothbrush comes with an all in one toothbrush head, charging glass and a travel case. It has a next generation motor technology that delivers up to 62,000 brush head movements per minute. It also has a touch screen display, 6 brushing modes (clean, deep clean, sensitive, max card) and a 3 level pressure light ring at the bottom. I connected it with the app for real time tracking. It has a brushing session timer and also tells you how many sessions you have remaining with the brush head. My teeth feel clean and fresh after each use. Brushing experience feels gentle rather than being harsh on my gums. The glass charger adds a bit of an aesthetic sense to the overall product.
