Review (4/5): Only one tiny detail.........
The Sonicare Essence 5500 Power Toothbrush is everything I wanted it to be, with one exception. The 30 second "beep" that signifies moving on to the next quadrant needs to be a little louder. But, hey, I can live with that because this product lived up to its hype, and my teeth have never felt cleaner. Well worth the purchase.
