These don't work. Period.
They absolutely don't work. They don't keep deer, squirrels, fox, cars, or anything else away. I had a sonic repellant before that worked, but it died after a few years, and I wish I could remember what kind it was, but this sure isn't it! I could literally hear the old one that I had when it went off. This one does nothing. Waste of money.
