I got one of these awhile back and it's the catz-azz for quickly removing the little bolts that hold body-work, seats, and side covers in place. It's also pretty good for clutch covers. It's good for anything that's not torqued super tight with a fine thread requiring lots of rotations. It doesn't work well in super tight places, but where you can get to the bolt, it makes the work go pretty quickly.
I try to keep a 1/4" and a 1/2" socket adapter handy along with a battery drill.
