Love this but for a different reason. I bought it with the intention of putting it under my area rug as my older dog pees randomly  constantly, and am trying to prevent ruining the hard wood floors. Totally without logic, my husband put it on top of the carpet (... I have no idea what he was thinking!) but saw the dog peed on it the next morning. Now we put it over the carpet every night, and wake up every morning to a gift. Obviously we’re not using it as was intended but we’re loving it none the less.
