I know this type of product for several years. I even found an old (the cube) stored in a crate and still works after 5 or 6 years. Is it really effective? I'll be honest in saying that I do not know, but when you hear the sound that comes out (thanks to the button that permits), I'd be a mouse that I would leave there. The product is absolutely silent in normal use and a priori no effect on a pet.
