Rated 4.1 out of 5 by 171 reviewers.
Rated 5 out of 5 by A better garage door opener The Chamberlain 1/2hp garage door opener improves on the technology of the keyless entry system since it can learn an opening code for both a limited amount of times it will respond to that code, or be set to recognize one as long as you want it. The bar that connects the motor to the door is also much stronger than other models I've had. No wobbling chain or buckling of the bar. It also has a feature that allows you to adjust how high the door goes when opening, and when to stop on closing. March 7, 2014
Rated 5 out of 5 by A great Murphy's Law purchase - very pleased with all aspects of this opener. Great overall purchase. After having our car sit in the hot sun for 5 months due to a cluttered garage -- we finally took a day to get the garage re-organized and our car back into it.....just to have the garage door opener break the very next day. Installation was easy enough and was done in a little over 3 hours...given the 'to be expected' minor adjustments needed when retrofitting a new opener. We had to make some adjustments to the existing mounting brackets in order to accommodate the new opener -- but everything we needed to make this work was included in the box. We were also pleased that we did not need to redo/replace the existing electric eyes and could use the ones already in place as they integrated perfectly with the new opener....saved some time. Overall the new opener - even though it is a chain drive - is quieter than our old opener. We also like that it has two light bulbs to help with overall garage lighting. The external opener was easy to install and program and we liked that the two in car openers were already programmed to work with the door. We haven't utilized the MYQ technology so we can not comment on this feature. Again - very easy installation overall - with great performance. Good purchase...and our car was back in the garage by the end of the day. August 5, 2014
Rated 5 out of 5 by No problems, works like a charm. Installed 2 of these myself, simple enough to do. They work great. Stay away from using a staple gun, can cause shorts in the system. These are pretty quiet and I love the keypads to operate the openers as well. All was easy to install, instructions were easy to follow. First one took about 4-5 hours, 2 took <2 hours. April 8, 2014
Rated 5 out of 5 by nice product very functional I bought this because the one I had was 50 years old no safeties. I did a lot of research and this seemed to be a good choice. Nothing from the old one matched the new one so I started from scratch. It took me about 3 hours to install. No problems,instructions easy to read. Everything functioning. The outside keypad is a good idea. You'll like this opener. June 24, 2014
Rated 5 out of 5 by Nothing better in this price range ! The old product was not built to the quality of the new one. This new garage door chain drive is super quiet. All the automatic safety features work perfectly. The setup was remarkably quick and accurate (at the push of a button, the garage door was accurately set for stopping at the correct levels for closing and opening. The remotes felt "lightweight", and it's quality was solid, which I also appreciate. I felt that I could toss a remote into my briefcase and it not feel like a "brick". All the controls worked and once learned, it was easy to use and instantly memorable. The bottom line here is that Home Depot bought a high-quality product like they always do (I will always suggest that you as a buyer, do your homework before buying anything. Yes, I would highly recommend this product at any time. December 5, 2014
