Review (5/5): good
i have never used a power tooth brush before, so i have no basis of comparison, but i think it's quite good.
some people said it takes a while to get used to, but that's not the case with me...
it comes with one brush head, and there are several alternative styles to choose from when you buy more...
i noticed my teeth become just a little bit whiter every time i brush.
when the battery starts to drain out, it gets weaker, so you know when to recharge.
