Rated 5.0 out of 5.0 by Works perfectly, easy to install, plenty of options The gate operators were reasonably easy to install, excellent instructions, plenty of options for installation issues, and plenty of options and accessories for operations. Operators are slightly noisy, I didn't expect that they would make any noise. As to durability, time will tell. December 23, 2014

Rated 5.0 out of 5.0 by Very Heavy Duty You get want you pay for on this one. This is a great opener. The darn thing is so strong it will almost move a house. Be sure to follow the instructions on the DVD. October 16, 2013
Rated 1.0 out of 5.0 by would return it if I could This gate open is slow and very unresponsive. Even had the installer come back and move the antenna box up hoping that it would work better. You have to right at the gate to get the remote to open the gate. I am NOT happy with this product I even spent extra for the heavy duty on thinking it would work the best, but it does it.

Rated 5.0 out of 5.0 by I found the unit easy to install and maintain I have had our units for just over 3 years, they were easy to install and maintain. The only thing I have had to do is replace the backup battery this year. I have recommended these units to family. August 31, 2013
