        Pretty good polisher
        I was very happy with the (big) size and excellent battery life. It uses a standard 5/8-11 thread for normal accessories, so you don't have to run the supplied backing place, you can use conventional detailing tookls, But, the speed ranges are far too high, and using the variable-speed is to touchy to realistically slow it down. Even on the lowest speed (800 rpm), it was WAY faster than I would normally run. It's possible to feather the trigger to get variable speed, but the range of the trigger is very small, and takes a very delicate touch. I can't imagine using any of the higher speeds on a car or other paint, you would burn through in seconds if you get it set wrong.
