Review (4/5): Environmentally correct power toothbrush
Finally, a decently powerful toothbrush that uses replaceable rechargeable batteries. I always felt bad about throwing away perfectly fine equipment that has bad built in batteries.
After using this awhile, I can see why some reviews have problems with the battery compartment. However, I don't brush my teeth in the shower and I dry the toothbrush after every use so so far no problems. Also, there is a flat surface on one side of the device so you can lay it down without it rolling. If you store it that way between uses (or upside down as some people suggest), no water can drip down to the battery opening. Agreed, though a better opening for the batteries would be a screwed cap with an o-ring. Other nits: brush is on smallish side and expensive.
