Philip’s Sonicare 9900 Prestige

The toothbrush has some fantastic features including a long life battery but combine this with Philip’s App and the brushing experience is completely enhanced. With the App I soon realised that I was using too much pressure and it also guides you on how much time you spend brushing in one area too much or too little. The end result is a fantastic feeling that my teeth are absolutely clean and you clearly see this on the app. It essentially trains you on how to clean your teeth. I would highly recommend this toothbrush.

Pros

Great quality and the best toothbrush I’ve used so far.

Works well

I’m pretty happy with the performance of this device. It’s light weight , easy to use. I like that the brushes are easy to detach and easy to clean. I like the app tracking of your brushing time and technique. I like that you don’t need to use the app if you don’t want to . I like the different programs and timers. I like the long battery life and how it is compact and easy to travel with. I only wish the replacement brushes would be cheaper .

Pros

Easy to use. Choice of different programs . Lightweight. Long battery life.

Cons

Very expensive replacement brushes.
