If they work, I use them around my workbench. Otherwise, I take the back off, pop the motor out (and slam it to the ground to break off the blades), then stuff it full of anything big enough to not fall out. When it's full, I screw the back piece on, and presto, I've got a convenient way to carry a bunch of those odds-and-ends that are always piling up on the floor. Also, this increases load density in my van.
