DOES NOT WORK if ...
If your hair is naturally straight and/or fine, it won't even grab the hair to roll it.  It's too hot to touch so you can't help roll the hair up onto the brush. When I finally was able to get my hair rolled up, I held it for a count of 50 on it's highest setting and when I released the hair there wasn't even a wave, let alone a curl of any kind. I returned it. Expensive but doesn't work if your hair isn't long, coarse or already curly.
