It's loud and sensitive enough. They don't turn off just because the pressure is removed, you have to physically turn them off. I prefer it this way. It's a decent deterrent for cheap.
These give me a great sense of security when traveling.
Used this alarm over a 2-week whistle-stop vacation. I had no false alarms. I tested it at home before the trip, and even with industrial hearing protection, it was quite annoying--impossible to ignore.
Very nice security devices. I like That they have sensitivity settings so that I can put one under my front door and the cat won’t set it off. They are quite loud, much to the dismay of my landlord who came over while I was at work.
