Ah they're just toys to me. I could run the dog I used to have into the wall with it, but my new dog is too smart for that.
I did get to use mine as a deterrent one time. A group of "homies" were bothering my son and kept driving by or sitting in front of the house to intimidate him so I put the laser inside with them one time and voila' they wanted to leave and never saw them again for some reason???
