FREE: Garage Door Monitor (Is my door open/closed?!)

The listing, Garage Door Monitor (Is my door open/closed?!) has ended.

This Liftmaster "Garage Door Monitor" works on *ALL* Overhead Garage Doors to tell you whether or not you left your garage door open - from anywhere in your home!

It's a simple idea - but ingenious. The smaller transmitter slaps on the inside of your garage door (with included double-sided tape, or screws - not included), and when the tilt sensor inside of it is triggered, the receiver inside your home lights Red/Green for Open/Closed.

The receiver plugs into a standard AC outlet with the included transformer. The transmitter requires a battery, which is also included in the package.

Now, the package is sealed (the plastic box is scuffed, but the product's in great condition), the other image is stock, just so you can see the set better (power adapter not shown).

If you'd like more information, there is a PDF of the included instructions, which answers everything:
