Has anybody used one of these things? It looks like a car antena on a platform and on TV it rips the bones right out of the fish. Anyone actually own one of these things? Do they work?

I'm not mentioning the product name because I tried this post on another BB and the mods removed it because the product has a funny name and I guess the mods were worried that someone would make a joke....heavens forbid. Anyway I'm not trying to start a joke thread I just want to know if this thing works. Many thanks
