I, personally became a believer of the electric impact at ZUK's place. I held a carrier/ring gear assembly in my left hand, and zapped off the factory ring gear bolts with the impact in the other. Nothing but a little vibration. I know that attempting that with my air gun, the assembly woulda hurt my hand and flung to the floor.
