I really like the idea, but the fact that it is "as seen on TV" and "not sold in stores" concerns me. If it were sold by a manufacturer that I am familiar with, I think it would be worth twice the price. Their pro model is supposed to handle a 300 ft lb impact. I really have reservations about that. Other than that, it would really be a nice thing to have where a pneumatic ratchet is just a little too big.
