They are nice, I think it just depends on the way you wrap your hair. Your hair should be pretty dry after showering (or you can sprits it with a spray bottle) also depending on how thick or thin your hair is will depend on how long you need to keep them in. They are ok to sleep in. If you have them tight it is a bit uncomfortable though. I would suggest finding a friend who has some first and ask to borrow them for a day to see how you actually like them. Everyone's hair is different.
