Q: This book has some good basic information on the subject, but does not give enough depth or detail of each subject area to make it well worth buying. It's very basic, so I'm sorry I bought it. I'll go back and get something more detailed when I've had a chance to use this, as it's useless sitting around being passed from one person to another.

A: Bad review

Q: I am on my 3rd power cord. The first one burned out after only a couple of months. Amazon sent me another one. Only lasted 3 months and now has stopped working. This cord also gets really hot. Not sure how this got such high ratings. Wish I'd never bought it. At least it was cheap! :(

A: Bad review
