A word from a user

“This Mighty Mule gate opener works great for me. I have an almost 900 pounds 20-foot sliding gate and it seems to open it fairly smoothly and quickly. I was honestly very skeptical at first when examining the gate opener when receiving it. To me It didn’t look very tough but I was wrong. It took me about 6 hours to install it by myself. I also used the cement mounting post for this unit and the mighty mule wireless keypad and pole that goes along with it and they all work great. Great customer service as well.”

“Overall, I love it. We got a huge sliding gate (probably around 700 lbs) and this device is moving it without any problem. Installation takes some knowledge but manual is mostly well put together. The manufacturer’s website is very supportive if you run into any issue.”
