I got a Buster Food Cube quite a few years ago as a Christmas gift from a friend of mine and it's been a huge hit with the dogs ever since. They go crazy for it, knocking it all around the room. I love the fact that they have to work at it to get the food/treats out. It's a great idea for dogs who eat their food to fast, just fill the Buster Cube with their normal amount of food and let them work to get their meal. My one complaint is that the Buster Cube does make a lot of noise when the dogs play with it downstairs on the hard wood floor and it does make it a bit harder for the dogs to get the food out so they normally play with it upstairs on the carpeting. I also like to fill the Buster Cube up with treats and give it to the dogs before I leave the house so the dogs can play with it while I'm not there. That way they aren't getting into anything else in the house and actually do something instead of laying around the house all day.
