They are pricey, but my dog really likes them. I save them for when I am at work. Just makes me feel like he's getting a bit of mental stimulation when I'm gone. But, Baxter is a little 7 lb. havanese. Not very 'handsy' so it takes him longer to get the bones out. The toy gives him about 15 minutes or so of hunting.... The spinny is the easiest. We have the tornado which is the hardest---- not so hard that he hasn't figured it out, just it takes him longer
