Ok, this thing has made me famous/notorious in my neighborhood. I bought it as a 'reminder' to dog owners to move on down the street instead of leaving their deposits on my front grass. I know, I know, everyone you talk to 'always' curbs their dog, right? Yet, somehow I still had piles of poo on my lawn. I thought this might be a harmless way to discourage that, since my friendly little 'no-poop' sign was summarily ignored (even cleaned up a pile right next to it once). Well you can adjust this thing pretty well. It's a circular pattern, but you can set the stops to form a wedge shape. The motion sensor works pretty well, the range adjustor isn't perfect but it's pretty good. My grass is a strip right next to the street though, and I could never get this thing to ignore cars or people walking by. If I set it too low, it wouldn't 'see' dogs walking on the grass. YMMV. Regardless, I became known as the 'sprinkler house' in the neighborhood. Kids loved it during the hot weather -- they'd run by again and again setting it off and giggling. Others thought it was a clever idea. Others were annoyed that it went off whenever anybody walked by. One woman timed the motion sensor and let her dog poop on the grass and didn't pick it up. When I 'asked' her why soon thereafter, she said she 'didn't want to get wet.' One punk kid who it got sprayed a 'very' little bit walked up on my grass and stomped it (didn't break it though, good build quality). Until they make one that can spray in a square pattern, this was my best attempt at a poop-free lawn. It still works, but I've stopped using it. I think most people are 'trained' by now and I got tired of telling the story to neighbors when they would realize I lived in the 'sprinkler house' :)
