These little things are awesome! I have them on all my kids windows and my doors so I know if they have been left open or if someone comes through my door at night and they are super loud! Which I seen a lot of people complaining about but if someone breaking in I want it to be loud my bedroom is in the back of my house and my kids are in the front so I’m not able to hear what’s going on till I got these now I sleep so much better at night! My neighbors can hear these go off when I was installing and messing with them which I love in case anything ever happens.
