Excellent Toothbrush!
My dentist highly recommends the Sonicare line, and I can honestly say that my dental appointments have been much nicer (i.e. lower numbers of problems) since I started using them about five years ago.  This model is great in that it has the automatic beep every 30 seconds to let you know to move to the next quadrant of your mouth.  The smaller head also allows you to get into the more difficult-to-reach parts of your mouth.
