I'm not going to bother commenting on the content of this DVD, because even I feel it is an insult with all the errors and factual mistakes. First the most annoying error -- he has a group sitting in one room talking about the Holocaust without noting that almost every person who ever worked for or was persecuted by Nazis was Jewish, making no distinctions at all: they were all Jews.

Ex Output:
Bad review

I needed a replacement after my cats ripped through the cheap one that came with our kittlery. This is better constructed than similar priced ones, appears to be of good quality, works as described and was reasonably priced.

Ex Output:
Good Review

This is a cheap knockoff - no doubt they made money. Please don't buy this product as I did in addition to the one that comes with kindle. It does nothing at all and only lights it up by going into sleep mode..its worse than useless... waste of money for sure!
