Been eyeing one of these for a while now. Finally cashed in some Home Depot gift cards and got one. Neat, but pretty low powered. I didn't consider that it has NO ratcheting action or hold, pure impact power. Kind of cool but it won't replace anything I have already. I feel like it might be better than an electric in a very few applications. I'll have to try it on different stuff and see. Right now it looks like an electric ratchet is much more useful. This is 3/8". They also sell a 1/4" and I quite frankly can't picture that on being useful at all.
