If you are too stupid to be able to tell if somebody is trying to sell you something, you deserve to be taken.
I read Ohgizmo because I like to look at cool stuff that I'll probably never have any intention of actually buying.
And if a commercial happens to slip in there... so what? I'm not a moron and I'm not gonna buy anything pricey unless I've checked it out from multiple sources.
These things have been around for years. Think I got my first one around 1995, give or take a few years. They do work better than any other can crusher I've used. And they work even better with a bit of modification.
