Rated 4.0 out of 5 by 9 reviewers.
Rated 5.0 out of 5.0 by Easy to program Programming was easier than the instructions. It just works. February 17, 2015
Rated 5.0 out of 5.0 by Works perfectly I bought this system so I could know if the garage is closed. So far it has worked perfectly and saved me from more then one midnight run downstairs to verify the door it closed. The installation only takes a minute and the programming of the base unit to recognize the add on is simple and easy to do. December 17, 2014
Rated 5.0 out of 5.0 by Does the job Garage monitor used to sense two garage doors, easy to install add-on sensor. The range of the monitor extends over 50 ft, even thru several walls. Cost is reasonable. Highly recommended. November 4, 2014
Rated 3.0 out of 5.0 by Limited Range I received the garage door monitor with my purchase of a Chamberlain Whisper-Drive garage door opener. I purchased this Add-on sensor for the second door of my garage and was able to pair it easily to the system. However, the range of the system is rather short and it took me a week of moving the receiver around the house to find a location where the receiver would not lose contact with the sensors. I even purchased a new battery for each sensor to be sure the limited range was not a weak battery. It wasn't. Seems to be working as intended now that I located the receiver in the corner of the family room closest to the garage doors. Make sure you have an electrical outlet inside the house close to the garage doors that is convenient for you to monitor the garage door status. Will not work in your upstairs bedroom or even on the opposite side of the house from the garage. December 13, 2010
Rated 5.0 out of 5.0 by Excellent working, Compact Clicker I have owned Chamberlain products for about 18 years and in most cases, they have given great service. The 3 button Mini Multi Function Remote Control is the best Remote Controller I have ever purchased. We are going to purchase another one, right now. Thumbs-up all the way product December 6, 2011
