SlabQuest, I used 3 mag20s for a year and didn't like them,for one the only way to lower the ball is power down,...slow.. then the down -stop -up switch is way to touchy. Sometimes you can't find stop and it just slams back-n-forth between up and down...what a drag.. ...at $800.00 give me a brake....scottys work everyday....and you save over $300.00 each unit.
