I had bought one for some of my routers 25years ago before variable speed routers came out. It was less than this one and they do work good if you have to dial a slower speed in. Most routers are running at least 10,000 rpm and you can bring it to a dead stop with this type. Mine you can clip on to your belt and reach down and adjust the speed.

For carding I use either burlap or denim, also the grey Scotchbrite pads. On the ribs, a fine wire brush.
