Your assuming only people with a sense of humor playing a "best joke of the day" prank is buying products like this, thats rather naive of you. Plenty of twisted minds are buying it for more than a gimmick and its no jokes about psychological harassment! Why be a contributor to selling stuff like this only thinking good people are buying it for a joke? As soon as the lights go out it emits a high pitch sonic energy, so does that mean its always going off in the daytime since the lights are always off during the day? How terrible for the unsuspecting target.
