I have two long haired cats and these are by far my favorite lint rollers--super sticky and gets the job done in record time.

Ugh! What a steaming pile of predictability this movie was. At least I didn't pay to see it and was able to read a software tech manual while "watching" this. The plot is thinner than the paper it was written on and the acting, well its typical Michael Bay which means you can see more believable productions at you local high school. It was easily an hour too long and the special effect have been used hundreds before. I think the saddest part was hearing Lenard Nimoy as Optimus Sentimental, I mean Sentinel. Gratuitous sci-fi pandering at it's lowest.

Ex Output:
Negative

Dr. Bernstein is a type 1 diabetic and had just about every sympton possible. He figured out the "diabetes code" and clearly explains how to control your diabetes. His cure is exactly opposite to that of the medical establishment. He was educated as an engineer, then became a medical doctor late in life. His book is designed to educate and not to impress how smart he is. Buy it.David Smith
