Product Description
Amazon.com Product Description
Right up there with "Did I leave the burner on?" on the list of nagging questions, "Did I leave the garage door open?" vexes even the most responsible of homeowners. That's why anyone with a garage should consider hiring a sentry--a Garage Sentry, to be specific. With a wireless range of up to 300 feet, the Garage Sentry monitors whether a garage door is open or closed, then alerts the homeowner of the door's status with a single beep. Installation is easy, too--simply attach the battery-powered sensor to the inside of a garage door and plug the receiver into an electrical outlet. One receiver can monitor up to four garage doors at once. Considering the number of valuable items stored in a garage, why not rest easy and let the Garage Sentry keep an eye on things?
From the Manufacturer
Don't leave the largest door in your house wide open! Great for workshops, homes or business garage doors.

Disappointed,
By A Customer
This review is from: Design Tech 30300 Wireless Battery-Powered Garage Sentry (Tools & Home Improvement)
This item is not dependable. I needed a device that worked as this one is described however after numerous false readings over 2 days it became clear that this item is not effective. Save you money and manually check to see if the door is open, this item is sure to disappoint.

Quality Control Problems,
By Mortgage Guy "richa65" (Duluth, GA USA) - See all my reviews
This review is from: Design Tech 30300 Wireless Battery-Powered Garage Sentry (Tools & Home Improvement)
Seems like a simple enough device, but the unit shipped to me simply does not work. I played with it for a half hour going thoroughly through the instruction manual, checking the battery voltages, etc, but the transmitter would never register with the receiver. Oh well, buyer beware.

I love this item. Have had it for two years. My garage door was left open all night lots of times because I forgot it was open. Now the sentry tells me when the door is open. It works really good. I consider it a "must have" for folks with attached garages where they can't see their garage doors to know if they are open or not. Have also given this as a gift and everyone we give it to loves it.
