Rated 5 out of 5 by from Helpful company I was having a little trouble with the installation so I called in and ended up talking to an extrememly helpful tech service person. Now my gate opens flawlessly and I haven't had an issue since, I will definitely do business with this company again.

Rated 5 out of 5 by from Excellent Gate Opener This is the 2nd one I have had in 20 years. You won't be sorry. Keeps unwanted guests and sales people out. I have the dual model and it works great. You must get Automatic Gate lock with this dual opener. People will try to seperate two gates to slide through. Great unit "Outstanding"

Rated 5 out of 5 by from Even the best has room for improvement The Positive: As a contractor I see products a bit differently. To start with the openers are everything they say! Easy to install and operate smoothly. I am sure a home owner will have little problems installing them. The Negative: The company advertises them to work with up to an 18' wide gate but doesn't provide enough wire on the slave opener to even come close to crossing the driveway and making it back to the control box. Splicing underground takes special connections to keep the joints dry! A small issue missed in the instructions was when you have gates that swing away from your property and you want to reset the stop limits reverse the gate location from what is printed in the manual.
