Essential Info

The Universal Garage Door Monitor works with any overhead garage door. Mount the sensor to the back of your garage door with the included Velcro strip. When the door opens, the sensor moves into the horizontal position and sends a signal to the monitor that the door is open. The monitor then provides simple, visual cues to indicate your garage door's status: When the light flashes red, the door is open; when the green light is on, the door is closed.

    The item arrived quickly and without any issues.
    HJS -- United States   1/12/2014
    Got it yesterday. Installed sender with screws and was ready to go in less than 10 min. It's served it's purpose twice so far. Ain't the prettiest but I'm forced to look at it as a reminder every time I walk past the dining room. For the price this may potentially save me thousands. A+++
    MyName -- Virginia   10/24/2013
    initially worked well. but with the passing time begun to eat batteries faster and faster. looks like the sensor cannot handle to heat on the garage door, and the transmitter frequency drifts.
    InfoDiva -- Connecticut   8/27/2013
    The thing lasted two weeks on the garage door. It fell off and of course I didn't realize that until I had driven over the thing. Simply junk.
    PAUL -- levittown, NY   8/11/2013
    Don't waste your time or money. Worked for the first few hours then flashed an error signal. Tried all trouble shooting. Still no good. Exchanged for another unit which did the same thing.
    PAUL -- levittown, NY   7/20/2013
    Very simple to install. Green light for closed door and red for a open door. Occasionally both lights flash. Don't know why. Double face tape that was supplied is useless. Sender kept falling off of the door in the hot weather. Not a big deal. Just had to put a few screws in to secure it to the door.
    RC -- maricopa, AZ   5/17/2013
    Great product, quickly shipped and received. Minus 1 star for the garage door mounting. . .in 100 degree Arizona heat, the glue melts and the sensor hits the floor. Needs a "hard" mount cradle.
    Mike -- Calif   5/1/2013
    it would be better if it had a buzzer or something when ever it changed from closed to open along with the light.
    ANNE -- woodstock, IL   3/3/2013
    Easy to install and works great...love it.
    TIM -- westfield, XX   2/21/2013
    This is a simple but usful device. I always got upstairs and wondered if the garage doors were shut, now have this next to my bed and no more trips downstairs.
    ROBERT G -- indianapolis, IN   2/1/2013
    product works as advertised. sticky tape is unsatisfactory to attach to garage door. Product should have provision for screws to attach it.
    DEB -- phoenix, AZ   1/22/2013
    excellent device! easy to install. brings peace of mind knowing that the garage door is shut at night and not having to go downstairs and check. thank you!
    FRANK -- meriden, CT   12/16/2012
    This product does exactly what is was advertised to do. It was easy to install and was the best value I could find anywhere. I even ordered an additional sensor for my second garage door and was very satisfied. I keep an extra remote garage opener in the house and can open and close the doors as needed without ever going outside. It solves an age old problem at a great price.
    JOHN -- south lyon, MI   9/16/2012
    My previous monitor was attached to my garage door with the adhesive that was supplied in the kit. After 2 or so years, it fell off...onto my wifes car I suspect and that was good bye monitor. I had heard that the adhesive failed on your unit and was a customer complaint. To avoid the same problem I used (2) small screws and attached the back plate to the door...Let you know in a few years if the new attaching system worked...
    SCOTT -- carol stream, IL   8/19/2012
    I had one of these when I originally bought a Chamberlin Garage Door Opener. It worked well and was simple. The only drawback is that when the battery died it failed in the green or closed position. You need to check it from time to time. It need a battery life warning!
    JANET -- kirkland, WA   4/28/2012
    Exactly what I needed....I sometimes forgot to close my garage door and now I just have to look at my monitor to see if it is open or closed....thanks
    CHESTER -- slingerlands, NY   3/24/2012
    I COULD NOT BE MORE PLEASED. EASY TO INSTALL.
    DENISE -- los alamitos, CA   3/16/2012
    Great product at a great price.I thought I would have to invest in a security camera to avoid running to the front of the house many times per day to check the garage but this works like a charm.
    GABE -- cape coral, FL   3/14/2012
    Bought this to replace older unit that was well over 10 years old.....very satisfied. Every home should have one. Gabe in Cape Coral, FL

    easy to install and works great.
