Not comfortable for me [SEP] I certainly do like the idea of this non heating hair curler. But as one who often shampoos at night, t does have some holdbacks for me to give it a 5. I did not find it easy to to use, but maybe it's just me. I'm older perhaps than the target buyer, and I also have some shoulder problems that make it harder for me to reach around to the far and back side of my head. It takes a LONG time to dry your hair. Even wearing overnight was not long enough for me. It was not comfortable to sleep in, so I would not do that again either. I find that when I have the time, not going out for a few hours, it works OK if I air dry my hair till still slightly damp, add some voluminzing mousse and let it dry from there, about and hour. On the plus side, this method did give me a lasting and loose curl. So I would use for special occasions more than all the time. May also work for touch up curls between washings. Will try that next.
