Jason: Easy install. Little noisey but all in all no complaints. 7hrs to install including removing the old one. Running wires and setting up the motion detectors as my old system did not have that. 8 foot high door but returned the extension kit as I did not need it. Like the coded remote outside!

Marvin Lawley: I had a 40 year old Sears 1/3 HP that has worked for years which I only had to replace the worm gear inside the unit to keep it working and I would still be using it today BUT I think I my have thrown the remotes I had out when I was cleaning my garage out. So good luck finding a replacement. I tried a few that I ordered from Amazon but no luck and since Sears is now kaput you see my point. So I decided to try this model. It had several options, one I really liked is switching from chain to belt but since E Chaimberlain my old Sears was chain I went that direction. I truly like this model. It isn’t that expensive and it works perfectly with my older garage doors. It was a little difficult to get the first one up and running but with the new chain that was provided in the new kit I simply needed to remove some links and I had it working.

I took the old unit down which was easy, removed the top bolts and swung the whole assembly down since the rail is set up on a pivot which really makes it easy. Loosened the chain and slipped it off the main drive, removed both bolts holding the rail on and Sears is no more.

The Chamberlain came with a new chain, a new rail, a wall...

John Swanteck: I bought this opener to replace a 20+ year old craftsman model that seems to have trashed internal gears (the motor runs but the drive gear for the chain does not). I found everything in the box as described in the offering on Amazon. Everything works as described and the documentation is quite good - proper English, descriptive, detailed, and accurate.
For the installation I cheated. When I removed the old motor and set it next to the new kit I noticed that the drive gear was exactly the same. Looking at the chain I realized that it is really just a long bicycle chain and this may be a standard. On closer inspection, I saw that the mounting bolts for the new and old drive units were in the same places. In fact, the bolts were exactly the same. I read through the directions and saw that the installation matched every existing component in the old opener except for some small differences in the brackets that attached the chain to the traveling slide and that slide to the door. All I did was loosen the chain, attach the motor, tighten the chain, and it just worked with the old chain, rail, and door attachments. I DID have to replace the old opening switch, add the optical...
