This is the worst "hair iron" I've ever used. I originally bought it based on magazine descriptions/articles, especially the one about this hair iron being used on Jennifer Aniston's hair, by her hairstylist, and a picture of her great hair next to the product. I used it and no curls waves or even correct flattening. AND I do know how to use hair irons. This is the most amped-up talked about hair brand of hooey. One of my degrees is Marketing, and all I can say is these people did a pretty good job of making a big deal about nothing in the hair world. These products can also be bought at Sephora--which speaks highly of this company. I wish I took it back, now I'm stuck with it. Do yourself a favor and get a CHI CHI Nano Technology 1 inch Ceramic Flat Iron--a real hair iron, those people don't even need to over-advertise, their product speaks for itself.
