For $30 you cannot make any sense out of these CDs. Their supposed help section was obviously setup for their own benefit.
Bad review

This a disappointing book.. No real plot at all. Slow and boring. Was this suppose to be some new twist on a true story? I have read every single novel Mr. Brown has written, however after reading this, it is definitely my last.
Bad review

I purchased this item for my son and its not the right charger for his computer because it uses two prongs, instead of one prong. I have to return it. Now that I am writing this, i will be out a lot in shipping, so why bother. Amazon should review their vendors better. This was either false advertising or incorrect product description. The cost vs. value isn't worth spending the extra money, especially when you buy something through mail order anyway.
