Anybody use a HitchGrip?

I store my hitch in a locked coupler as well. The HitchGrip tool is of little use when doing this because it grabs the ball, so I made my own carry tool. I can't understand why most folks don't do the same because it is a theft deterrent for both the hitch and the trailer, it keeps the ball clean, it is out of the receiver and doesn't mess up any storage area.
