Rated 5.0 out of 5.0 by Easy to install, does the job After struggling with which gate opener to purchase, I finally came back to the Mighty Mule FM500 and purchased it. It was easy to install and is working as promised. Time will tell if it holds out. So far so good! January 3, 2015
Rated 5.0 out of 5.0 by Easy to install, works great I have a 13' steel gate that's trimmed out in bamboo and some redwood. It's not that heavy, maybe 200 lbs. The FM500 has more than enough power and pretty good speed of opening. This is a nice product it works great. October 20, 2014
Rated 5.0 out of 5.0 by Couldn't live without it!! We live in an area with a lot of rain and have large heavy gates at our property entrance. We installed this Mighty Mule and love it. Works great on the heavy gates and no more getting out of the car in the rain to open the gates. It works perfectly in our application. December 10, 2014
Rated 5.0 out of 5.0 by GREAT SERVICE!!! Simple to order, fast shipping, plus a free bonus part!!! What more could I have asked for!!!!! June 6, 2014
Rated 5.0 out of 5.0 by Efficient-Fast-Less Expensive than Costco My Mighthy Mule FM500 died a sudden death, unexpectedly. I needed a replacement. Bought the whole gate opener which is just a little more expensive than the control box alone. Disassembled the box and the electronic board and replaced into the old one and in about one hour with the help of my wife we installed it and works again perfectly. Now I have a extra opener.
