It's OK, very uncomfortable to sleep with.
OK this hair rod is OK in a pinch while traveling. I put a t-shirt on my head to sleep because I have layered hair and some of my hair was trying to unravel. It takes a few tries to see how to correctly twist your hair around. The front of my hair is OK but the sides and back doesn't look good. I'm assuming just like all things if I keep trying it may look better. My huge Con is how uncomfortable it was to sleep. I'm not a back sleeper, I sleep on my stomach or side and having this on made it really hard to sleep. I've used lot's of other sleep rollers that I could actually sleep with (rods, sponge rollers) so I'm really not sure I can suggest it because of the loss in sleep. Good luck hopefully others find this helpful.
