Rated 4.5 out of 5 by 15 reviewers.
Rated 5.0 out of 5.0 by Staying Warm and Dry It is so nice and convenient to have an electric gate opener. We replaced a single gate with a double gate and were very happy that we could reprogram our existing remotes to operate the new system. We also have 2 existing solar panels so we had to buy a new battery (the system came with 1 battery) but that was no big deal as the batteries are very reasonably priced. We also chose to buy a second key pad so that our visitors could get out as easily as they got in! We are extremely happy with the new 2 gate heavy duty Mighty Mule automatic opener. January 27, 2015
Rated 5.0 out of 5.0 by comfortable security Very satisfied with the overall results but as a DYI project it was hardly as easy for me as the video would have you believe. I'm a pretty handy person but found almost every step shown was not like my situation and required hours more work to complete ie, a concrete driveway which required cutting to bury the slave power cable, a sloping steep driveway with high walls on both sides requiring all work to be done from one side, well, you get the picture. But even with all that, this product does the job very well and I would still do it again. Your situation has to be easier than mine was. October 14, 2014
Rated 4.0 out of 5.0 by Works as advertised Installation was easy - instructions were right on. It has been working without any problems for about two months. It is slower than I would like and sometimes when using the remote transmitter when approaching the gates it starts to open and then stops at about 6 inches requiring closing and starting over. I have not determined if my vehicle is interfering with the signal or not. If I come to a complete stop it works ok. Overall I am happy to have it. January 22, 2015
Rated 5.0 out of 5.0 by Amazing product!!! I love this opener! Works great! Easy to install, if you know what you're doing. Directions are easy to follow. Watch the DVD too. Very informative!! I pulled the video up on youtube, on my Ipad so I could have it at the installation location. October 7, 2014

Best buy that I could find.Highly reccommend.I am 74 yr old with severe disabilities and the install took a little more time, but was not the fault of the opener.I am proud that I was able to do it by myself.
