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 ordered the product based on positive ratings - which was a big mistake. My husband worked with both types of products and never heard anything about this product. He tried it one day to give him relief after being in agony for several days and could not tolerate either one. Perhaps we received a bad batch? We will be returning them.

A: Bad review

Q: This product was very easy to set up (took about 30 seconds) but the remote control didn't work after 2 months! I called customer support and they had me do what he said on page 29 of the manual: take a look into reset button, etc. Even though this did not work, their tech could only suggest that it might have been "user error". It's an okay product, just beware while setting up. It definitely deserves one star for faulty product.

Bad review
