A sad look at a poor man's version of Michael Moore's "Fahrenheit 911" that leaves out some very crucial historical fact.

Bad review

This TV has pretty good picture and it is a great value. Amazon delivered with this product as promised. The only drawback I experienced was that the stand came without all of its parts, so we have to find some hardware at Lowe's for about $40. Fortunately, our other television is compatible but there are no speaker options on this model. All in all, though, very happy with it.

Ex Output:
Good Review

It's ok to read but for a book about dog training it didn't seem like there was a lot of specific info or guidance. There is one very simple sentence that helped train my dog, and then it's the same things every week. Glad I bought it used. Good luck if you buy new. But this was helpful in some ways. We have a new puppy right now we needed help with potty training.
