Rated 4.5 out of 5 by 11 reviewers.
Rated 4 out of 5 by all works well...... took me about 2 days to make adjustments like hanging the gate, etc. So far all works well. Only problem so far is that on rare occasions, it does not close automatically according to the time programmed. December 17, 2014
Rated 5 out of 5 by having gate opener means no one has to get wet i had no problem with the product easy to install amd to operate December 17, 2014
Rated 4 out of 5 by Excellent Equipment but not easy to install Excellent design, materials and install kit. Not easy for this DIYer probably due to the challenges on my site. December 10, 2014
Rated 1 out of 5 by NO Contractor will install I purchased two of these units on sale, Upon contacting a local fence company to install some fencing and new gates they informed me they would not touch the Mighty Mule. Then another and finally a third fence company. They say they get NO support from the manufacturer. I fear I am stuck with some junk, too late to return probably. May try and install with help of an electrician and some friends myself?? Not off to a good start thought... October 8, 2014
Rated 5 out of 5 by Makes my life easier!! We had a manual sliding gate and installing this Mighty Mule has made my life so much easier!! It was fairly simple to install but is pretty sensitive to any drag on the gate. We have a 16.5' gate and had to reinforce the gate post so it would hold the gate up without sagging. (Could be the fault of the fence installer!) We have installed the solar panel as well and so far the charge is perfectly adequate for our needs. Closing time needs to be quicker and we are having bit of difficulty with that....dogs will get out if gate is open too long. Overall I LOVE this thing! September 24, 2013
