Yeah, this pillow pretty much sucks. In addition to it being a tiny, crunchy, heavy bag of buckwheat husks, it doesn't even live up to it's biggest claim: "Keeps your head cool through the night." I did not find this to be the case at all. In fact, I would say this pillow retains heat better than most synthetic fibers in pillows. I tried it out for as long as I could bear (about 20 minutes) and you can clearly feel the pillow heating up to your body temperature. Dr. Watanabe is selling snake oil.
