Rated 5.0 out of 5.0 by UnicornHall Chamberlain Garage Door Monitor
I park my car, enter via the front door, and then close the garage door from inside. What was happening is that I kept forgetting to close the garage door and leaving it open all night. I wanted something simple and silent to remind me to close the door, and nothing that required an entire alarm system addition (other solutions required sensor to be a piece of an entire monitoring system). The stand-alone Chamberlain was just what I needed. A sensor simply sticks to the garage door and causes the inside monitor light to go green when the door is down, red when it is up. You do have to find power for the inside monitor, but the garage door sensor is battery driven. I rated Quality with four stars only because I haven't had it long enough to see how well it lasts (but I'll buy another just like it when it wears out).

The garage door monitor by Chamberlain takes minutes to install and gives you the piece of mind you want when you can't see if your garage door is closed or not. For those of us that walk into the house and then think "Did I close the garage door?", this is your solution.
The small transmitter mounts quickly and easily to any garage door with the included adhesive "hook and loop" strip. Make sure to install the transmitter with the curved side facing the bottom of the door so the internal motion switch can operate properly. The battery is included, it's a lithium coin cell size 2032.
The receiver mounts to any wall using a small screw. It mounts just like a smoke detector. Adjust the flexible wire antenna into an L position to guarantee it can pick up the signal from the transmitter. The receiver has a plug in power pack, so you'll need to install it within six feet of an outlet.
Once installed and the receiver is plugged in it automatically picks up the signal from it's matched transmitter.
When the door is closed, the light on the receiver base stays solid green. When the door is open, the receiver base will flash red. It takes just a moment to see if you closed your door.
My garage is over 50 feet from the receiver and I've had no signal issues. We've had temps near zero lately and it still worked perfectly.
I'm glad I got this. No more wandering outside at night to see if I in fact closed the door. One look at the light gives me my answer without ever leaving the house.

Rated 1.0 out of 5.0 by MartyG Poor Design
Great idea, poor design. The sensors work great on the garage doors, but don't transmit very far. This only works in the room closest to the garage. This was not designed by anyone mindful of interior design. The cord and the wire antenna come out of the top, so have to be routed down and around. The power outlet is black, not white. Do you know of any interior walls in America that are complemented by a black, dangling cord? The wire antenna works fine for a garage door opener mechanism, but looks terrible in a house. The LED lights are dim. Too bad this is the only manufacturer who makes such a product that I know of.

Quick to install. Technology is simple and seems effective. Can't comment on durability (too soon to say). Garage door component is unobtrusive and attaches easily. Indoor component is no more tacky than some other stuff we've got (obvious white plastic gizmo is far from elegant, but it's not supposed to be jewelry; nevertheless it's most useful if it's reasonably visible somewhere we pass on the way to bed (so we don't leave door open at night -- that's the point); so cosmetics are relevant. Main issue for us is no way to coil/retract the power cord so it dangles. Minor issue. So far it does what we bought it for.

Installed 2 sensors on 2 rollup garage doors, with a single monitor in the house. The sensor needs to be installed at a slight angle to trip the red light as soon as the top section of the door starts to tilt, otherwise that top section has to be almost horizontal before the red light comes on - allowing the door to open further than I wanted. Easy to install and it works great.

The garage door monitor only took a few minutes to install. I was cautious due to some negative reviews of the product not working after a few weeks. I've only had the product for 3 weeks and so far it has re-calibrated once and otherwise been working properly. So excited to have a way to monitor if I've left my garage door open!

I bought it to replace the LiftMaster monitor which has been used for many years but recently lost contact to the sensors frequently. After following the instruction to complete the initial setup, so far the device, monitor and two sensors, has been working flawlessly. No more communication loss happens i.e. the green and red lights flash intermittently
