Rated 5 out of 5★ by Itzerbitz Works great but ..... The only problem is that both pieces have to be lined up and at the same level/height. I was using on a door and the door frame and the door are not the same level/ height. I made it work by using my dremmel to cut out a notch a little wider in the door frame. I've attached a photo so you can see what I'm talking about. There may have been a better way but this worked for me. 02/03/2014
Rated 5 out of 5★ by Hla94 GREAT! I bought these for my sliding glass doors leading to my backyard/pool. My toddler will not go near the doors now these alarms work so well! Not sure of the battery life yet...but the sound is loud! Serves its purpose well. 06/27/2014
Rated 5 out of 5★ by Alarm123 Great alarm for the price. Have on my bathroom window and love it. Feel secure knowing the alarm is loud enough to hear. 06/26/2014
Rated 1 out of 5★ by CNWV Bad Purchase: Very poor battery source. After installing, batteries didn't last anytime. Should have returned but didn't. Wrong decision. 01/12/2014
Rated 1 out of 5★ by 3Squares I was looking forward to receiving this item. It does not work! It may be the batteries; which should be new but when I move switch to 'on' nothing happens. no green light, nothing! When I press the 'test' button, nothing happens! I guess I have to go buy batteries for my new device..... sooooooo frustrating!!!!!! 10/22/2013
