Review (5/5): I LOVE IT!!!  It is fun to brush and makes my gums feel good
I bought a two pack for both of us and we both love it. It has a 2 minute timer built-in and every 30 seconds it will beep telling you to move to a different zone. The zones are bottom inside, bottom outside, top inside, and top outside. It is even smart enough to run at a slower rate when you first get it and after a number of brushes it will move to a higher speed. I thought I brushed well until I got this but now I know better. I cannot say enough good things about the Sonicare.
