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.

Pressure feature
The toothbrush is light easy to hold. I really like the touchscreen where you can adjust all the settings and it tells you how many more cycles you have left before you need to replace the head. My favourite feature is the pressure detection. I had been brushing my teeth too hard as I had some blood in toothpaste before now I know the correct pressure it’s all clean. My last favourite feature is the timer once 2 minutes are finished the toothbrush stops and displays a smile which makes me want to brush my teeth for full 2 minutes every time. My teeth feel very clean and fresh. The charging glass is a great touch. My favourite toothbrush brand

Toothbrushes
A premium electric toothbrush which effectively and efficiently gets the teeth clean. It has multiple speed settings which you can adjust to your preference. The toothbrush instantly tells you how much pressure you are using and if you need to adjust. This set came with 2 toothbrushes , a charging stand and a charging cup. It's water resistant, and not too loud. My teeth feel great and much cleaner. It's super handy to have the app which tells you how you are cleaning and which areas could do with more time.

The Philips DiamondClean 8500 HX8596/21 is super amazing. It's so gentle on my teeth, yet gives the most amazing result. It's easy to build and maintain. It's good value for money to spend on your oral care. I absolutely love it.
