As Seen On TV

I'm a big skeptic when it comes to "miracle" home improvement products. I recently read a story about those products you see on TV (Magic Putty, Stick N Click lighting disks) ... 95 percent of them don't work. But I found this one online -- called Rejuvenate -- and thought it looked interesting. Has anybody ever heard of it? Ever tried it?

What about other products you've ordered via TV/infomercial? Have any of them worked?
