Extraordinary Essence
I really like this powerbrush. My previous brush was the Sonicare 4100, and it was good, but I find the Essense e5500 easier to maneuver (less bulky), and seems to be more effective in removing plaque. It is easier to brush the back teeth, and behind the teeth.  It is rapid, and that takes a little getting used to. It does seem to work quickly to "toughen" the gums; the first few times I used it, it hurt a little; but then no problem. Overall, I'm quite pleased.
