Ditto to what everyone else has said so far. They have a sweet video of those blades takin the heads off, but I don't think it would do any good on a body. Lets put it this way, if I had to be shot in the chest with a broadhead, that would be the one I would want to be shot with. Yeah, it may stun me and tear me up, but I don't think it would be able to penetrate all the way into my vitals and I would have a better chance of living.

Haha. I don't reccomend anybody testing out my theory though!
