For the most part, assume that anything on an infomercial is junk. There are exceptions, but very few. Ask yourself this question - think of how quickly products like Rogaine and Viagra received wide publicity and acceptance. Why did this happen? Because they work and the fact that they work is easily demonstrated and documented. Now ask yourself how easy it should be to demonstrate and document that this "ab-belt" works as advertised? Now ask if there is any reason that the media wouldn't jump on it as quickly as the other products if it did?
