Amazon.com Product Description
Sometimes you just forget to close the garage door. But if "sometimes" is closer to "usually" for you, you may run the risk of having your garage emptied out by opportunistic passers-by, and you will certainly pay more to heat your house. Chamberlain's Clicker Garage Door Monitor helps you minimize the likelihood that you'll leave the biggest door in your house open. The device mounts easily without tools to your garage door via a Velcro strip; if your door is open, the sensor sends a signal to the monitor, causing a red light to flash. The monitor may be plugged in anywhere in your house where you're likely to notice the flashing light. Depending on your garage-door habits, this device could help prevent theft and lower your heating bills. Includes lithium battery.--Josh DettweilerWhat's in the Box
Sensor, receiver, AC adapter, double-sided Velcro fastening strip, lithium battery

 Works As Described, Bought Two More September 6, 2010
Gearhead (FL)
This Garage Door Monitor (GDM) works as described. I bought a total of three units. All three have been working for for over six months with no problems.
Two were purchased from Amazon. One is the neighbor's who wanted one after his garage was pilferred after leaving his garage door open all night. We combined our order so Amazon gave free shipping. I gave the other to my son who has a young family and has left his garage door open all night also. The third that I use came with a new Chamberlain garage door opener I bought locally and installed. We are all happy with the GDM.
They were easy to install. Just hang and plug in the inside unit. Then install the battery and attach the door unit to the garage door with the velcro sticky tape, you are done in ten minutes. The hardest part is figuring where to put the inside monitor.
I live in Florida and the garage gets over 100 degrees. The door gets even hotter since it is a metal door exposed to the Florda sun part of the day. Imagine touching a car sitting in the sun. The unit works fine in the heat and transmits to the receiver about 50 feet away. The signal has to pass from the garage door through the garage wall (cement block), accross the outdoor front patio, then through a second cement block wall, through the living room, then through an inside drywall wall to the receiver in the bedroom. More than once it has alerted me that the garage door was open.
My preference would be a simple plug on the inside unit rather than a transformer plugged into the wall. I just hung the monitor about socket high which beats hanging the thing eye level on the wall with a bell wire to it.
Installation considerations September 1, 2010
Jim (USA)
I'm really pleased with this purchase. I live on a very busy street and over a couple of decades I've lost an expensive bicycle, a drill set, and a heat gun due to accidentally leaving the garage door open.
I just installed the Chamberlain Monitor so I can't comment on longevity, but I was concerned about the many reviewers who have reported bad installation experiences.
After installing mine, I suspect that one of the most common causes of problems is poor placement.
Attach the sensor to the garage door at the highest possible point where the sensor is still in a vertical position. That way, the garage door will have to be completely (or very nearly completely) closed before the sensor will be vertical. (Otherwise, the garage door could be partially open and the sensor would still be horizontal and register "closed.") Also, in this position the sensor will be as high as possible for ideal reception by the receiver.
Place the sensor on the garage door as close as possible to whatever direction the receiver is going to be in. That is, minimize the distance between the sensor and the receiver as much as possible.
But also be careful to position the sensor so that there are no metal or other super hard materials in the line of sight between the sensor and the receiver. Be particularly careful to consider the metal rails and rollers at the edge of the garage door - metal will obstruct the signal.
The sensor operates on a round lithium 2032 battery but the receiver must be plugged into an AC outlet - it comes with a transformer and a 5' cord.
Place the receiver in your house as high as possible and in a position that is likely to have the most unobstructed line of sight between the sensor and the receiver. A 9" relatively stiff wire antenna is attached to the receiver. It comes coiled - stretch it out carefully, removing any kinks so it will be as long and as straight as possible. Position the antenna so it extends straight up from the receiver.
My receiver is positioned on a wall in the kitchen about 7' high and about 35' from the sensor. There is a workout room and a clothes washer/drier between the garage and the kitchen so I was careful to position both the sensor and the receiver so the signal wouldn't be obstructed by heavy stuff. One of my walls used to be the stone exterior of the house so I couldn't get around that - but the signal seems to be making it through just fine anyway.
I first taped both the sensor and the receiver in position so I could test the setup a few times before permanently installing them.
One final note: A small piece of Velcro comes with the sensor for attaching it to the garage door. I'm not convinced that this is going to be a permanent solution since we often have 100+ degree days in our town and the Velcro adhesive may not last long. If it doesn't, I may just reattach it with a dot of super glue to the adhesive side of both pieces of velco - we'll see.
That's it - hope this helps.
Works just fine August 30, 2010
Stuart Goss (Robbinsville NJ)
Installs easily in minutes and works perfectly. Green light on remote monitor shows when garage door is closed and red light shows when door is open. Change in door position from the vertical when door is opening is sensed by simple internal switch in the sensor. Very reliable so far. Cannot think of any negatives at all.
 Doesn't work August 27, 2010
HKSac (sacramento, ca, usa)
It worked fine for about a week, then it started blinking red/green regardless of the position of the garage door. Tried unplugging and re-plugging which fixed the problem for about ten minutes and then it went back to blinking red/green.
Pretty much worthless for indicating the garage door position. Don't think distance is a problem since it's only about 25 ft from sensor to receiver, with only two interior doors in between.

Great product! Easy to install and easy to use. What else could one want? Also reasonably priced. Install in 5 minutes and now I know the garage door
is down with just a quick glance at the monitor before I go to bed.
