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 Dettweiler

From the Manufacturer
Did you close the garage door after you put the mower away? Go check now... You back? All good? Phew! But for next time, save yourself an unnecessary trip out to the alley with Chamberlain's garage door monitor. The garage door is big, and tough to forget to close. But, when you do, it's very likely that all those valuable tools, bikes, skis, and whatever else you keep in there won't be there by the time you realize what you've done. Chamberlain's garage door monitor lets you know if the garage door is opened or closed without the trip out to the alley in the middle of the night. The system installs easily with no tools. Just set up the sensor on the door, and set up the monitor in any room in the house. A flashing red light on the monitor means the door is open.

Customer Reviews

Worth the money spent
It isn't the most robust device, but it was worth the money spent on it. The sensor attaches to the garage door with sticky back velcro. This makes it easy to remove to change the battery. I put it on the top of the door, so it will indicate open as soon as possible. Range seems sufficient. The only unknown is how long the transmitter battery will last. It uses a nickel sized lithium cell.

Update 2006-10-25: I still don't know about the longevity of the transmitter battery (still going strong), but I have loved this unit for the past few months. It has become a little "confused" two times over the last 6 months. It would indicate open, when the garage wasn't. I unplugged the base unit and immediately plugged it in and all was fine. I would purchase this again and wish I had done so sooner.

No problems
I received this item three weeks ago. Installation was easy and the unit worked as specified. I didn't have a problem with any distance, however my garage door is only about 50 feet away from the base unit.

You do have to plug the base unit into a wall outlet and it has a slightly bulky transformer. I didn't know that when I purchased it. I thought both units were battery operated. So you can't just hang the base unit up on a wall in the house somewhere.

Overall I gave it four stars.

A little more cosmetic boost is desirable
I have left open the garage door a couple of times after I left home for work. And I found my neighbors left open theirs even late in the night. That's why I decided to search for a garage door monitor.

Among all the sensing method available in the market, this tilt sensor is most robust and does not affect by installation dimensional tolerance(means easy to install and fail-proof.)

It works as claimed. But the design has some more to go. The color is not creamy white, which would blend well to painted common household drywall. It is rather grayish white, like office equipment. And the wire to power adapter and the adapter itself is black. It it would have been white, it will be perfectly blend into house interior.

The price is somewhat high, considering the simplicity of this thing. I think total accquasition cost should be $30 for it.

Anyway, it will be a useful helper for who is forgetful or busy to take care all small things such as closing the garage door. Again, because I have seen my neighbors with open garage door by midnight, I believe mine will keep such a thing from happening to me.
