[Q]: This was a bad buy. It did not work properly and I am very disappointed with it. Not good customer service. After hours of troubleshooting we realized the unit needs to be returned for replacement. Hopefully it will end up working properly.
[A]: Bad review


[Q]: This was really not worth my time and money. It made for a good coaster though! I wouldn't waste your time. Just wasn't what I'd expect from such an acclaimed author.
[A]: Bad review


[Q]: I can not believe amazon would sell a book that the author himself admits contains misinformation and outright lies. This is the most despicable act of deception I've ever seen! You are cheating American citizens out their hard earned money. Do you honestly think people don't have this knowledge or will they trust someone with this?Shame on you!
