I thought it was Karen because my new neighbors thought it was neighborly to drive their race car on the other side of the fence 20 feet from my office and bedroom window . I usually hate Karen and really don't want to be one of them, but sometimes life throws goats at you that shake your house to the ground when you're trying to sleep and you have to put them out of your misery. This handy little device was the best I've spent for $20 in a while, and also kept those neighbors nice and quiet now for fear of violating noise ordinances. I hope I don't succumb to this fall of power and become a full Karen.
