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.

A: Good Review

Q: I have had the machine for 13 1/2 months and it worked well at first. Now, a couple of weeks ago, one side started acting weird. If I hold either button, then pull up all or don'thing, there is no heat from the surface. It just stays off. So, today when my husband said something about heating pads, you can see where that went down. We are pretty much out $200 to spend on another microwave. You would think that this company would be able fix their machines after so long.
