[Q]: This book was written in the 70's by a man who knows his stuff, which is a rare find nowadays. The problem with it is that he relies too much on anecdotal stories and anecdotical sources to support his hypothesis. It feels like reading someone's blog, not science. Also, some of the anecdotes don't make any sense unless you can explain away how they happened.
[A]: Good Review


[Q]: The light is really bright but its not very durable. It does work pretty well considering I have a few things on in my kitchen because it's kind of dark here during the day.
[A]: Good Review


[Q]: I had ordered this item twice from Amazon. When it first came in, the box was a bit dented but not badly enough that we could tell what condition it was. However, when my dad opened he saw there were holes in it, so apparently somebody tried to remove it. We put batteries in. The mouse itself stopped working after about 5 minutes and then just went dead. It is VERY cheaply made. Not to mention now Amazon wont make things right with me or refund my shipping.
[A]:
Bad review
