I often times have bad dreams and sleep not very well. Besides, I am eager to know how many times I move my head during the sleep. That is why I decided to by this wonderful Pillow to measure sleep quality. I have seen many types of gadget pillows that were useless but this one is amazing. This pillow, I think, is somewhat useful because it actually gives you information about your sleep.It measures the depth of your sleep by measuring your head movements. There is a theory about the quality of the sleep: The less you move your head (or your body) while sleeping the better sleep you had. This pillow simply counts the quantity of your movements and shows you if you had a good sleep or not in the morning. I think that this pillow is really cool. I was experimenting on myself trying to find out when I sleep better. I found out that I sleep better when I am tired than when I am relaxed, and I sleep better when I am a little bit drunk. You can make the same experiments to find out everything about your sleep.
