It works!
Second vacation trip I've used this on. Goes off at slightest noise or wind blowing against door. So it works great that way. My one complaint is battery life. Only lasts for about three weeks.

Simple and great solution.
Wonderful solution for my deaf son who does not hear the knock at his door. I love the portability of it, too. He has been using it for a couple of months now.

Not the best to have. The slightest movement would set the device off.
