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.
