Cat treat toy opinions

I am looking for a toy that dispenses cat treats. I have seen several but don't know which one would be best. Has anyone found one that they like? I tried to make one by cutting holes in a plastic container, but it was too hard for my cat to get the treats so she got frustrated and did not have fun with it. Plus the only treat my cat likes are Liv-a-littles, so the toy would need to work for that. (freeze-dried chicken, about a quarter to half-inch wide, I can break them to any lenghth). I am just trying to give her something fun to do, for change in routine.

Thanks!

I made my own version of a treat dispensing toy with a paper towel tube with appropriate sized holes cut into it. It took one or two demonstrations, but Marcie played with it all evening until she destroyed it and then I just threw it into the recycle bin
