I have had this Buster Cube for years. I first bought it for a dog, but my curious cat took it over and loved getting his treats out of it. Then it sat waiting until I got my heeler mix dog who needs indestructible toys that challenge him. I put half of his breakfast in the cube every morning. He rolls it, picks it up and drops it, noses it, pushes it with his feet - it keeps him busy so that I can eat my breakfast in peace. Well, relative peace. I have plush carpeting, and when it gets onto the vinyl it is indeed noisy. I don't care, however, because my buddy enjoys it so much. For this dog in my circumstances, it's a 5-star. I down-rate it a little because it isn't for every dog in every situation.
