PROBLEM: This is a great way to protect your ipod by only adding about half an ounce of weight per device. Plus it's more stylish than those cheap leather cases. I highly recommend it for anyone who wants to take on the protection and fashion quotients of their ipod. It can be folded in half which makes taking photos much easier.

SOLUTION: Good Review

PROBLEM: Poor quality! Plastic frames broke upon putting on these glasses. One fell off and then broke. Not worth even the price. Returned this item... too bad, because the glasses looked great!!

SOLUTION: Bad review

PROBLEM: I purchased this book on my kindle when it was available. The price made me skeptical... but like always there are people who just know what they want. Well, you won't need to worry about buying this piece of garbage. It may have been written by the author but, alas, not only did he write it, it's pretty boring as well. There's nothing new or interesting here that hasn't already been covered a million times around the campfire and in hundreds (if not) of other books for sale.

SOLUTION:
Bad review
