Really good, but not ideal if you have thin hair [SEP] I purchased this product because i was so tired of constantly spending at least an hour of ironing my hair. I thought this would speed up the process. All in all, the product is really good. It heats up quickly and shuts off automatically after a while, only thing is that my hair is really thin and the bristles of the brush is really thick so whenever i brush my hair with it, my hair barely catches to the brush. Still a good buy though.
