I got mine in last week, finally found time to wire it up, and it works great! I tried it both on one of the knobs and a spare stick on my 9ch, no problems with either. One thing that I found very nice is that it has a nice wide neutral area. If you are using a 2 axis stick (like I am), with one axis for steering, and the other for the winch, you don't have to worry that every little twitch up or down on the stick will result in winch movement. The only thing, and this is just because my truck is so darn long, that I wish was different is that the wires overall were about an inch longer. However, my winch is 18 inches from my receiver, so most people should be fine!
Thanks very much, I'll be doing business with you again!

edit: I'm using this on an RC4WD Bulldog 9300 winch, which had horrible creep with the stock controller.
