I have long straight hair, but with this curling iron I create absolute dream curls. And the best: they also keep for several days. The device is very hot (Warning finger!) And thus must each strand roll up only briefly. It heats up very quickly and I need therefore no longer than 20 minutes for a great hairstyle. I use the curling iron very often and can not say that my hair would take them damage. Hot blow dry is probably much worse. Very convenient is also the supplied bag.
