Negative Positive
Title: Amazing little gadget
Review: These little alarms are great, you can't believe how loud they are. I find it reassuring that I'd know if somebody tried to open the door while I was asleep. I don't expect them to keep out someone who was really determined to get in, but they would sure as heck advertise that they were trying to do it, and that's all I ask. They are good quality and easy to set up.
