[EX Q]: If this were not for the review by Steve R.
[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]: I have used this same one for years and when my last two were stolen, I bought another. The plastic is cheap and breaks easily. They need to make a better one.
[EX A]:
Bad review
