[EX Q]: I bought 2 of these radios and at 1st i was happy with them but after a few weeks the sound became distorted (crackling etc) when playing songs or using in stereo mode on FM. You have to turn both radio's off and back on, then they resume normal. Tried upgrading firmware without any luck, tried multiple frequencies still not acceptable. Now one radio doesnt detect FM radio stations at all, cannot scan for weak signals. A poor purchase!
[EX A]: Bad review

[EX Q]: The plot is not interesting and the characters are uninteresting. Although I got it in advance from Amazon, probably would not pay too much for it. Not a great read.
[EX A]: Good Review

[EX Q]: I have to agree with some of the other reviewers. The print is small, and there are MANY typos that a spell check won't catch. It's hard work, especially if you want to read anything above your level on this one subject. However, it IS thorough, and the price was low enough for me not feel really ripped off. Edit: Also, all of those little questions in parentheses seem like they were just thrown in, because it's been more than two months since I bought it.
[EX A]:
Bad review
