Also, does anyone know of any good websites that test all (of some) of the products you see advertised on late night TV, to check if they're as good as they say or just frauds? Always thought that would be a good website to have. I'm sure if you looked up an individual product you could find all sorts of info on it, but I think it'd be cool if there was a website with all the info gathered in one place.
Do a Google search for 'infomercial reviews' and you'll find quite a few such sites.
