It will only run when the Haus machine is running. We used to have the kit on our Haus until we bought another Haus. The first Haus is still running great in another pro shop. The kit actually pulls back one of the wheels for a second which allows the ball to spin in a different direction. Hope this helps.

Who needs a 300 or 800, when I have a 294 and a 295!?!?!
