These don’t fit all my doors due to the door facing not being even with the door. My garage entry door is the only door that works. I think it’s because this door doesn’t have a glass insert but I’m not really sure. The alarm is loud enough that I can hear it in the other end of the house. If I could figure how to build up the door to be even with the door facing I could use them. I haven’t tried the windows yet..

the alarm sound is very loud and they don't eat batteries... however I'm down to one left because they break very easily and sometimes the sticky pads are squished up so they're unusable.......

One of the alarms works fine, but the other one is missing battery contacts at top end of alarm. Would love to have either a replacement contact or a replaced alarm. Would’ve given 5 stars is part we’re there AND working

I bought these when my son learned to crawl. My other three children constantly left doors open, including the door to our basement. This alarm is super easy to install, inconspicuous, and OBNOXIOUS. My children quickly learned to close the doors. Took less than a day. Now we don't even need to turn the alarm on. I still do when they have friends over to play with just a quick switch. I also love that they can be installed in different configurations for different doors, IE sliders vs traditional doors (see pics). These are life savers!
