These curling irons suck. Not only are they extremely damaging to your hair, they do not produce a good curl. The curls don't hold, partly because the thing doesn't even get hot enough, which it should after letting it heat up for 15 minutes. I have thick, long, wavy hair, when I use this curling iron, the curls fall out almost immediately. They fall apart pretty easily as well. the screws come out and the clamp detaches. I didn't even bother try the thing a second time; I just returned it. It is way too expensive for the mediocre job it does. There are much better products out there. It is extremely damaging, you'll find your hair dying a lot faster than usual. I do not recommend this product, don't even bother wasting your time or your money getting this product. The same goes for Hot Tools Flat Irons. I've tried hot tools irons in all different sizes and they all, for lack of a better word, suck.
