"I found the Mule easy to install. Once I read the directions setup was easy for me and no problem. The only problem with the gate was a cow that chewed the wires in half, not the products fault! I will buy another gate opener for my next project. Its been more then 2 years since I first installed it.

A worthwhile product, April 22, 2008
By Grandpoohbah from Ojai, CA

"Installation was surprisingly easy but learning the adjustment cycle took some time. The instructions do not emphasize enough how important it is to have a solid attachment to the gate, especially if your gate is at the limit for weight and size (as mine is); I have had to reinforce mine twice. Troubleshooting is a problem because the unit communicates with beeps and there is no guide in the manual, so you have to call the factory to find out if your one long beep or two short beeps or whatever is 'obstruction' or 'low battery' or something else. Once I got the alignment and closing position right it has worked well for nearly two years. The opener range is only about 40 feet. It is good value for the buck and I would buy another."

"Easy to install but only worked for two days. Tech support is quick but could not resolve the problem for several more days. They concluded the arm is defective. I have to dismantle it from the gate and return it. At my cost and with my own packaging. It will be 7-10 days to get it back. I would not buy this product again."

Close to a 5, April 8, 2007
By NFDFFP from CA

"The opener was easy to install. The video helps a lot. The only downside to this opener is the transmitter range. It says 50-100 feet, and that is generous. It is more like 35-40. It would be nice to be further away so you don't have to sit in front of it while it opens. Otherwise, it works like a charm."
