As an experianced mechanic and electronics tech I was very impressed with how well this garage door opener went together and the overall quality of the components. The assembly manual was one of the easiest to follow and understand I beleave I have ever read. Kudos to the technical writer who put it together. The only flaw I found was in reference to the trolly arm. It says there is a tab on both ends that needs to be bent up after the trolly is installed. Not so, there is only one the end that mounts above the garage door. Programming is a snap. No issues what so ever. The remotes and pin pad opener comes with batteries installed, ready to go. A word of caution. To open the remote controls pry on the bottom. If you pry from the top it will break the lock tabs. I failed to read that part of the instructions!
It's really annoying because the door will get almost all the way down and go back up!!! No rhyme or reason....except I found out on GOOGLE that more people have the same problem....and say the sensors are mounted on the garage door track and the vibration of the door going down can intermittently confuse the sensors. My garage door is a big wooden one so it's a lot heavier than a metal one...ergo more vibration. Recommendation is to mount the sensors on the wall somehow not the door track....
This is a great product. Works great and quiet too!
It is fairly quite and hasn't given me any problems. You must lubricate and tighten the chain when necessary.
So far so good, worked as expected.
This is a fantastic garage door opener. Easy to install, versatile, and powerful. The directions clearly explained the install process, remote setup and keypad setup. I'm sad to have sold the house I installed this in.
