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


Ex Input:
The title of this item is very misleading. I have found nothing more than "basics" to be offered in the recipes. It was not what I had expected from a new book. A cookbook that would teach you how to do all kinds of things for your family, but most importantly - recipes where there are no preservatives. There were a few things, such as a banana bread recipe and one on my favorite dessert, carrot cake recipe. But those weren't worth paying for. I'm sorry I bought it.

Ex Output:
Bad review


Ex Input:
These were a waste of money. They would be ok to keep the bugs away during a zombie apocalypse but are very cheap for how inexpensive they are! You get what you pay for!

Ex Output:

Bad review
