Helps whiten teeth every time you brush
Sonicare electric toothbrush with advanced sonic technology gently removes stains for naturally whiter teeth every time you brush.
Pressure Sensor helps protect your teeth and gums
Built-in pressure sensor automatically detects pressure you apply, warns you, and reduces the toothbrush vibrations automatically to help protect your gums. The toothbrush will make a pulsing sound as a reminder to ease off the pressure. 7 out of 10 people found this feature helped them become better brushers.
Makes traveling easier for you
Our premium travel case lets you store your toothbrush hygienically, while our compact USB charging base keeps you topped up when you are on the go. You do get two weeks of regular use from a single full charge, but the charger's just the ticket for longer trips.

Powerful dependable with crazy long battery life
This toothbrush is the best I've ever tried. It is powerful and dependable. It has such a long battery life I have to keep reminding myself where I put the charger. I especially like the feature that beeps every 30 seconds to let me know how much time is left, so I can adjust the speed at which I brush. I highly recommend this toothbrush to everyone.
Pros
powerful, dependable, long battery life, 2 minute timer with 30 second prompts

First time having one of these types of toothbrushes and so far I am enjoying it. If you press to hard it lets you know and the 2 min timers is a bonus.
