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 i did not find it easy to to use but maybe it is just me i am 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
