almost got to use mine last week. A quad had crashed off the trail down in to a ravine. They got the quad running and rode it out, so no need to winch.
I did install the wireless...it has good and bads. Good... Well, wireless. Don't need to find the controller and plug it in, and it has good range. The bad... The signal must send in long pulses, so when you let go of the button, it continues to winch for a second. Probably not a big deal, for actual winching, but gave me some trouble stowing my cable. I hook my end over to the tow hook, so I dont want to pull to hard and put a bend in the cable. Had to reel in and out a few times to get it right.
Second thing, now the controller is always active. So, im a wee bit paranoid about something bumping the button, and my winch unspooling while im doing 70 on the freeway. Imagine running over the cable....big wreck, lots of damage. So, the controller is living up in the garage door opener compartment in the overhead.
