[EX Q]: I bought this as a gift for my husband, but have already used it. Easy to use, easy clean up. Definitely recommend.
[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]: For the record, this set is not a complete collection and has some flaws.- Most of each program is about 15-23 minutes long and there are cuts from many programs during certain chapters- A few movies that have been restored with Dolby Digital 5.1 soundtracks (the original releases on Laserdisc had Mono soundtracks) do NOT sound as good in stereo since those discs utilize only mono audio so all but a bare bones surround system will be required.- The video quality varies considerably.
[EX A]:
Good Review
