I didn't understand why there was so much buzz around the Yaduo pillow a while ago; it felt like many were just following the trend. Then I tried it myself, and wow, it's amazing. Usually, I lie in bed playing on my phone for hours before sleeping, but yesterday, I lay down and fell asleep in just half an hour. I ended up sleeping for 10 hours straight and couldn't even get up. I highly recommend it; it's not expensive either, ranging from 200 to 400 on Taobao.
