[EX Q]: Do not buy this product. It literally falls apart like a piece of junk. I bought it in December 2009 and it's only been used maybe 5 times. Just yesterday the sound no longer worked when trying to turn on or change channels. This is horrible for anything besides show sound. Also some people who posted reviews said you couldn't use an ipod. You can't. Apple did screw up making that feature completely useless by adding this adapter instead of supporting it. When buying it, look at the price tag.
[EX A]: Bad review

[EX Q]: The book was easy to read, and filled with valuable information that is worth the time spent reading it. I bought it in conjunction with a project, and, as part of it, read this very good guide on how exactly they did things down there at Area 52. Not only does he get his information, but writes it in such an entertaining way, even for non-scientists.
[EX A]: Good Review

[EX Q]: I enjoyed this book and would recommend it. It's a great example of how to create an American literary classic in a relatively short period using contemporary slang or expressions that relate to the plot as well as some old-fashioned slang. The best thing about it is that it's not full of useless information. It contains all necessary information for an interesting read. For people wanting something very different, this may be your book.
[EX A]:
Good Review
