These are comically useless for us, but that doesn't mean they won't work for someone else. We bought two to keep our cats from tearing up our new couch, but they will actually go underneath it to scratch the couch still. They also look a bit cheap and don't offer a lot of color options, but that's not a huge deal. We got the gray ones. They're still on the couch, but I wouldn't purchase them again. They looked/sounded great in theory, but lesson learned.
