We got this for our toddler's room, in order to alert us when she got out of bed. After a few weeks, we took it off. When it worked, it was fine, but about 50% of the time, she opened the door gently enough that the alarm didn't go off. If it was a little more sensitive, it would have been great for us, and it would probably be fine for a "sticky" door that can't be opened smoothly, like a weatherstripped exterior door.
