Review (1/5): Poor Quality
Within the first month/ few weeks, the brush would stop working. The speed of the brush started off going slower, then it eventually progressed to not spinning at all. This is with using high quality batteries (like energizer and Duracell). After that, I figured I may have a bad batch of batteries, so I replaced them and within another month the brush started doing the same thing. I opened it and inspected the inside and realized there was water as well as a lot of rust on the batteries and the inside of the brush. I was able to get it working by cleaning off the batteries and rotating them, but it's only been working half performance since then (meaning to get the brush to spin, I have to continuously hold the button down). Last night the brush completely stopped working, even with new batteries. Take the money you'd use for this brush, save it up, and invest in a Clarosinic or another higher quality brush. I'm completely displeased.
