Great
I was asked by Philips to try the product and post a review. I’ve been really impressed with the electric toothbrush. What I particularly like is the range of different settings, as it means I can choose the one that suits my needs depending on how my teeth and gums are feeling. It’s easy to use and leaves my teeth feeling really clean and fresh. Having different brushing options also makes it feel much more personalised than a standard electric toothbrush.

Fantastic Product
What an upgrade! I’ve previously been using an older version Philips toothbrush and this is noticeably more powerful and effective. Lots of programs to choose from and the built in timer is really helpful. The charge lasts ages and the product itself looks really stylish. I have noticed since switching that my teeth feel cleaner. Super impressed!

This toothbrush is amazing; in just a week, my gums and teeth are in much better condition. I wouldn't trade it for any other.
