I searched about the benefits of buckwheat pillow before making the purchase. No complaints there.
The pillow arrived with very less buckwheat. I called hullo and had to wait for more buckwheat to arrive before I can use my pillow. It would be better if they send more to everyone instead of less. The buckwheat crushes with use and I find myself adding more every few months. I recommended to a friend and he also had to wait for more buckwheat to arrive before he can use the pillow.
I like the material of the pillow case but they sewed over the zipper, so I had to remove stitches to unzip the pillow case. Small details but it creates hassle for the customers.
