Review (1/5): Waste of $
It was comfortable to sleep in, but it doesn't really work. It's hard to wind your hair around it because you can't move the donut or really see what you are doing since it is sitting on top of your head with your ponytail already through it. It just looked like a large crease in a ring around the top of my head, as if I had worn a ponytail all day. Total water of money. Returned immediately.
