Review (5/5): Second Sonicare... Much Improved
Nothing lasts forever, and my old Sonicare that I had for over seven years finally wore out (the batteries would no longer take a charge). I've been a big fan of Sonicare for years, so had no doubts about buying a new one... the e5500 is much improved over my old one... it is much easier to keep clean and the thin neck enables you to keep your mouth closed during brushing so the toothpaste doesn't dribble down your chin. The Quad-Pace feature is great for helping me ensure that all my teeth get proper time with the toothbrush. I feel very strongly that if you follow the instructions, you will have cleaner, whiter, healthier teeth than just using an old manual toothbrush.
Excellent quality, good features, and perfect design!
