Review (2/5): Good idea but very uncomfortable.
I think this is an excellent idea for curls and heatless style. I wasn't able to use it, though, because the part that the hair wraps around is super hard. There is no way I could lay my head down on that. The only way this would work effectively, is if I wore it all day, for a night outing, or if I went ahead and used head and blow dried it.
