Rated 4 out of 5★ by LastMinuteDiva works pretty good This alarm system was pretty easy to install. My door and door frame are not very flush so I needed all of the shims that came with the kit plus some. I really liked the fact that it has an on/off switch. I can come and go without setting of the alarm and yet set it easily when I lock the door. It was worth the money. 11/13/2010
Rated 2 out of 5★ by jotee simple but too cheap made I have been happy with the window alarms but no so with the door alarm. It is very inexpensive but also comes with problems. Good things first:low cost, simple to assemble and to apply to door.Poor things second: The alarm side (with the on/ off switch) falls off the adheared part on door TOO EASILY, then you have to put silde it back on the unit. If someone opens the door and just pushes against it, it comes unclicked from the unit. (this piece slides into place on the part that is adhered to to door). I am dissaponted with the sound it is not loud enough, and only alarms for 45 sec. then turns itself off. To get a neighbors attention if you aren't home, or to wake from sleep , the alram sound needs to continue but it deactivates itself in 45 sec. This was not noted in the specifications.To feel safer I would invest in a more expensive unit than this one in the long run. I am using it until I can buy another unit. 03/16/2011
Rated 4 out of 5★ by PopPop58 Nice little unit. All plastic & takes batteries. It does what it suppose to. Not bad for the money. 06/19/2011
Rated 4 out of 5★ by Malistica Good for notification The alarm isn't to loud, but it works to let you know if someone is opening the door and would at least startle someone who didn't know what type of alarm it is 11/29/2012
Rated 1 out of 5★ by Ilikepauladeen Cheap! This is very cheaply build and the sound is not loud enough to do much good. Could be much better. If you want something that really works well, then DON'T GET THIS! 09/02/2013
Rated 4 out of 5★ by alarmednow good deal for the price Was a little tricky to get lined up to work. One I got that it worked fine 09/07/2014
Rated 4 out of 5★ by ilianacatspawn Easy simple installation Not as loud as I'd hoped it would be and it resets after 45 seconds automatically, but it does the trick. Easy to put together and easy to install. I'd definitely recommend it. 05/02/2014
