Great product. Easy to install. Gave me hours more viewing for my TV. This product improved watching HD programs with my new Samsung HDTV.
Good Review

This case is made of VERY cheap plastic. It broke while I was trying to get it on my ipod. The plastic breaks easily and can be taken off. DO NOT BUY!!!!!
Bad review

Don't even bother. It took all of a minute for me to realize this was a waste of money. I won't be trying any more products by these authors. This 'book' is about as long or longer than one page with some blank space at either end. If you want information, just go find it on the web.

Bad review
