Works great. The opener is really quiet, so it’s great...

Works great. The opener is really quiet, so it’s great. It goes up and down really fast and has a sensor for the kids so I don’t have to worry about it coming down on them... - 5 out of 5 stars / Full review

This is a solidly built motor...

I replaced our chain driven motor with this belt driven motor. I spent Sunday afternoon replacing the opener. It was challenging following the written instruction however when I went online and followed the video instruction it was pretty easy. At first I was going to reuse all the existing wires, but after a while I decided to use all brand-new wiring. Hooking up the electrical was a breeze. A big plus is that all the remotes came pre-programmed to the motor. Basically worked right out of the box. This is a solidly built motor.

Intstallation was easy and straight-forward...

Unit worked flawlessly for several months, then would not close. It went down to within a couple inches from the floor, then immediately opened again. After reprogramming the close and open limits, i finally called customer support. This really nice and knowlegable woman led me through a diagnostic procedure, then said I had a wiring problem. (The opener, not me). I checked the safety beam transmitter and receiver and sure enough a wire had broken at the connection. Stripped and reconnected it an the unit works great again. Kudos to customer support. Well done. - 5 out of 5 stars / DrJ
