Review title: Easy!
Product review: Wondered how quick my dog would catch on to this. She's pretty smart! She's playing with this a lot and knows that even though she can smell the treats better at one end, they only come out on the other. Luckily, it does take a while to get all the treats out. You'll need tiny treats for this. I got the Busy Buddie buddy berries (or something like that!).
