Query: Great idea, not so great execution

The Buster Food Cube is a great idea for slowing dogs down when eating. It is like a big puzzle to dispense kibbles as rewards. It has a clever settings system to make it easier or harder for your pet. I really wanted this to work, but I'm afraid the shape and slick plastic material used renders it almost unusable for our dog. There are not good gripping surfaces for the dog to get hold of. It is also hard to roll around a cube, especially a slick one. Of course the hard plastic shape is loud on wood or tile surfaces, again, making it difficult to roll over.I applaud the concept but our dog gave it two paws down. Maybe large dogs will have better luck with it.
