Query: Not enough stuffing

I was pretty disappointed with this product. For one thing, they didn't put enough herbal stuffing in it. It seemed to be only about half full. Secondly, what little there was all fell to the bottom when placed around the shoulders, which kind of defeats the whole purpose. I sent it back.As an aside, I was quite impressed with how easy Amazon's return process is.
