I like the size and apparent quality of Hullo. The buckwheat hulls are very poor in comparison to others I have bought since 92 when I injured my neck skydiving. The hulls are poorly milled and many are more similar to peppercorns than mere hulls. I notices a larger “grit” when sleeping but shook it off. Several days later I decided to remove some of the hulls to reduce the pillow thickness, and it was obvious that the hulls were poorly milled. I still have two of the older pillows and though they are a bit tattered now the hulls are much more comfortable than those in the Hullo.
