There suspend for me so far nothing at this curling iron. The heating process takes about half a minute with significantly shorter than in all aneren rods I've used before. The 5-level temperature setting also works easily and intuitively. Even the release of the curly hair from the rod works! Good thanks to the coating. I've already erlbebt different, so it finds mention in my review. The delivery is also a bag, which of course really would be good if they would be designed so that the unit including cable would easily fit inside. But that is the only thing I noticed is negative so far. So far a clear recommendation, because the result can really be seen.
