I would think you will have a good chance of breaking a screw with that. I've had a manual impact driver since the motorcycle days of my youth. You know those side cover screws, don't you.

And you didn't want to booger them up either. I'll stick with heat and the simple tool.

However, that tool is based on something I think we've all done. Crescent wrench on a square shaft screwdriver in one hand and a hammer in the other. At least he's not beating on his screwdrivers. So thumbs up overall.
