[EX Q]: Excellent for those of you who don't always go with the mainstream and like to take a different approach to their love life. Great read!!
[EX A]: Good Review

[EX Q]: It is definitely a unique design. Unfortunately, it does not function well. You have to be very precise with your touch and you don't really feel the brush on my teeth at all. Not sure how else I can complain about something when it's still working perfectly after several months. One of the things that makes this toothbrush stand out is that there is no battery. With other batteries, they inevitably fail or die because they're always sitting around. This one doesn't.
[EX A]: Bad review

[EX Q]: This one makes my wife extremely happy. I've been using it daily for the last two weeks without a problem. It's very easy to use. I have no complaints. It is small and light enough that if you lose it, it'll be just as easy. I'm not sure what else reviewers would want in an mp3 player. And at $24, compared with other brands selling for $40+, this unit provides pretty good value too.
[EX A]:
Good Review
