I'm probably overly cautious, and I've waffled on whether I really want one. I don't like the idea of drawing undue attention, but I also worry about some oblivious idiot suddenly walking behind me when I'm backing up. And I live on a cul-de-sac with lots of little kids around. Even though I'm always watching my mirrors and camera, I worry that someone will sneak into a blind spot. I probably don't need one, but it would give me a little peace of mind.

The interesting thing about the Brigade unit I linked to is that it's directional, so it supposedly isn't very audible unless you are directly behind the vehicle.
