Rated 3.1 out of 5 by 8 reviewers.
Rated 5 out of 5 by Easy to install. Works great. The garage door monitor kit was easy to install. Ensured the sensor and monitor settings were identical; attached the sensor to the garage door so the sensor arm extends fully when the door opens; placed the monitor in a visible location in the house; and, plugged it in. A green light on the monitor tells me the door is closed. If the door is opened, a red light comes on, and an audible alarm sounds (which can be muted if you intend to have the door open for a prolonged period of time). My monitor is next to my house alarm panel so I can tell at a glance if everything is buttoned up (and the garage door is closed) when I turn the house alarm on. April 3, 2012
Rated 5 out of 5 by very good purchase Good design ,price----recommend it to anyone looking for an easy way to monitor garage door status August 12, 2014
Rated 1 out of 5 by nuisance this thing works well, but is a nuisance. the audible alert is constant every time the door is opened. other brands are intermittent. who wants a loud alarm the entire time the door is open? I know it can be muted, but shouldn't have to do that. I returned it. June 30, 2013
Rated 3 out of 5 by ok product The only thing is that the sensor and the receiver can not be too far apart. Garage door is on the ground level, and the receiver is on the 2nd floor. If I put the receiver further to the back of the house, then it 'd give a false signal, meaning it just keeps beeping without stopping. So I have to put it in the front just above the garage door. I guess it is ok for now as of 02-21-2212. February 21, 2012
Rated 1 out of 5 by not worth it bought 2 of these they have not worked since I install them. May 1, 2014
