Rated 4.2 out of 5 by 186 reviewers.
Rated 5.0 out of 5.0 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 5.0 out of 5.0 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 5.0 out of 5.0 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 4.0 out of 5.0 by It Works! All of the parts were in the box, so that was helpful. We installed it for a 1 car garage. The metal parts used to secure the motor to the ceiling were extremely flimsy and we had to purchase sturdier ones before we could install it. Also, the sensors are extremely sensitive and the opener will NOT work without them. So it is a bit of a struggle to keep the sensors in place when using the door opener, the vibrations tend to move them out of place and if they are a fraction of an inch off, the garage door will not close. Very frustrating if you are running late or are in a hurry because you have to get out and adjust them and try and try to get the door to close. So, I suppose its good for safety! Other than that, It works very smooth and is quiet. I am glad I have it. Once I get all the kinks worked out with the sensors it will be a great product. November 7, 2014
Rated 5.0 out of 5.0 by Superior Quality and Performace I am pleased with the quality and performance of this garage door opener. It is powerful, quiet, and comes with an outside control panel and two remotes as standard items. I have a long driveway , and I can open the door well before I approach the entrance of the driveway if I want to. The inside control panel is lighted and has a separate switch for the lights that can be turned on or off regardless of the operation of the garage door. Programming the remotes and the outside control panel, as well as the setting up of the door operation was easy, and completed in less than 10 minutes. Installation: We upgraded from a contractor installed LiftMaster to the Chamberlain, so I had to remove the old system before installing the new system. At 66 years old, I was able to complete the whole process in about four hours. I even replaced the wiring to the sensors as the LiftMater used a different rail and wire routing than the Chamberlain . I used all the new parts that came with the kit. The rail and trolley system operates freely and smoother than the LiftMaster system did. I also installed more bracing to the ceiling of the garage to hold the chamberlain unit, as it is slightly larger and heavier than the LiftMaster was. However, the Chamberlain is quieter and more powerful than the previous unit even though the LiftMaster was rated at the same HP. I purchased perforated steel bracing, some bolts and nuts, as well as some Molly Screws from Home Depot, to assemble and install the bracing. The only issue I found was that the instructions did not mention the fact that the sensor wires can be easily threaded through the center of the rail, which worked quite well. I highly recommend this rather than trying to staple the wires along the ceiling of the garage, as is suggested in the instructions. I think this was just an oversight by the authors of the instruction booklet. Other than this the instructions were easy to follow and use. See the attached photos. Feel free to post any questions, and I will respond. February 28, 2015
