  1. Easy Straight Forward Install 5 Star Review

    Posted by on Mar 23rd 2021

    Install was easy and took about 1.5 hours per door. Only issue was that “cable tension” sensor was not able to be installed due to no room being available near cable spool and door wheel track brackets....I had to just block cable tension sensor open so it thinks there is tension on cable.....other than that, both installs were simple and all hardware was in package and remotes already programmed for door opener. Very quite opener and I really like the slow start and slow stop cycle...The door lock function is nicely done and works well.

  2. Easy installation, quiet and works great! 4 Star Review

    Posted by on Mar 18th 2021

    Opener works great (so far, only been a couple weeks) and Installation was very easy. Only one issue while setting up: I had pulled the release rope and when I reset it it didn’t go all the way back up. I didn’t notice at first so when I was running it I thought it was broken. Once I saw the slide on the side of the opener hadn’t gone all the way up I pushed it up and it engaged again. Following that it worked great and the rest of the set up was as described in direction! One other item is that you only get about 40 foot of bell wire for the control box so in order for me to make it reach was to hang it about a foot off the ceiling. Will have to get a longer roll of wire so I can string it along the wall or ceiling and not have it hanging. Overall I really like it so far!

  3. Good product, my second one 5 Star Review

    Overall I really like this door opener. It is the second one I have installed. And I have installed both myself. I like how it clears up overhead space in my garage.
