Rated 4.5 out of 5 by 11 reviewers.
Rated 4 out of 5 by Good quality and value The only reason I didn't give this product a 5 star rating was I had it almost installed and discovered the slave arm wire was 8 ft. too short. Called and they sent me another arm with the correct length wire without any problem other than the 3 day wait .it was easy to install and appears to be a quality product. works great July 16, 2014
Rated 4 out of 5 by Good purchase Must remove circuit board to view the serial number. Not good. July 8, 2014
Rated 3 out of 5 by Works fine but slow opening Works well. Opens very slowly. Customer support at Mighty Mule very responsive to unusual questions without a long wait to reach. Recommend if willing to wait for gate to open. February 20, 2014
Rated 5 out of 5 by Easy set-up and install Installation of an automatic gate as this product makes opening and closing a gate so easy. No more getting out of the car to open the gate in the rain, and added security to your property. May 13, 2014
Rated 5 out of 5 by Just what I wanted. Fast delivery, easy installation, works perfect. This opener is more than I expected.Easy to install, works great. 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.
