Review (1/5): Worthless Piece of Junk
This thing is a piece of crap. I put in a brand new set of duracell AAA's, it barely had enough power to spin the head against my teeth. So I popped those out and the spring contact flew out. Put that back in with a new pair of batteries and it still didn't have enough power to spin the head while applying minimal pressure to my teeth. My oral-b toothbrush is more effective, but I wanted something with a polishing cup that would be small enough to reach my back teeth.
I wouldn't recommend this to anyone, period. I've used it for less that a minute and it's going back immediately. It's pathetic.
