It keeps unwanted people out of my Apartment!!!

Had strange people walking in garage when I left door open , I live a 180 feet off road

The alarm tones are very loud so has to put some electrical tape over the speaker to quite it down some , but that isn't a problem most people would probably prefer the loud alarms

Might be too sensitive for some areas, minimal adjustments available, may require some creative adjustingAll in all, I would recommend if you need something reasonably priced just to alert you of encroaching people, vehicles, and animals

I wanted to use it to scare off people that were around an area that they shouldn't be.

People compliment me on how pleasant the sound is LOL.
