You were doing it wrong - When the motor's not engaged, you twist it like a normal screwdriver to loosen the screw and then push the button to do all the spinny work to take the screw all the way out. Same for doing it back up, you use the motor to spin it back in and then just give it a little manual twist to tighten. That way you're guaranteed not to knacker the head of the screw, over tighten it or strip the thread.I bought a Wowstick some time ago and it was utter junk. It didn't have enough torque to undo the vast majority of the screws I tried, even ones that weren't that hight when opened with a hand screwdriver.
