[Q]: Great product. Easy to install. Gave me hours more viewing for my TV. This product improved watching HD programs with my new Samsung HDTV.
[A]: Good Review

[Q]: I have the largest version, and for my purposes it is perfect. Only complaint would be that the sides are not rigid enough, so the top of your head will probably slip sometimes. It does its job well in keeping you dry (and it's very comfortable) when swimming. Would recommend even with small problems.
[A]: Good Review

[Q]: This was a complete waste of money...I don't think I will ever read it again. It was not worth what i paid for. A really cheap book. The ending sucked. It's like an author told her characters "hey maybe you should save your stories until closer to the end, because we didn't have time for good endings. And I'm going to get lazy and just cut everything off at the end." Do yourself a favor skip this one if you're interested in reading a book that you can finish.
[A]:
Bad review
