Ball Polisher
The price sure seems reasonable enough, and if more available they should be advertised in the publications as well. Nice job. The only (minor) drawback that comes to mind is removing the "hot glue" if ever necessary. Hot glue is the nastiest stuff I've ever encountered. Wouldn't Velcro work? The centrifugal force will keep the carpet in place. At any rate, for the price I'm certain they are an absolute bargain.
