I bought a My Pillow for myself and several family and friends. My sister and I do not like ours. It is better after fluffing and/or drying. The Casper pillow has been wonderful from night one. I merely fluff from corners as directed when I make the bed. Going to buy one for my sister's birthday. Highly recommend.
I like that it can be big or pounded flat. It doesn't determine how your head and neck rest, you shape it into what you need. Not perfect but the best one so far
