Title: Stripped teeth on coupler
Review: One of mine also stripped the plastic gear. What a terrible design, the piece that gets the wear from inserting different tools and takes all the torque from the motor is made of an inadequate piece of plastic or nylon that strips out far too easily. There should be a total recall on these or a class action or something. They are all destined to fail with much use at all. My faith in the entire brand has been tarnished. What a shame.
