We have one and it works great, very easy to set up. We had a problem with breaking the shaft that you chuck up in the drill. But now we haven't broken one in a few years. Other problem is if you look at the gearbox it has a ramped area to help make the rope not over lap, well after a while the rope burns in that and then the rope overlaps. I am going to machine that off and make it flat and then machine a ramp out of a hard plastic. Pricy unit but saves a ton of time. One big job like an appartment or hotel with a lot of feeders and it pays back pretty quick............Brian
