Review (1/5): So not buy if you have thick curly hair!
I have extremely thick and curly/wavy hair and this did not work. The control buttons on the side are consistently being touched with every brush. Had to constantly readjust the heat. My hair is still super wavy in some spots. I know these work because I had one for a year, but left it at the hotel and it went missing. I have already printed the return label and it arrived a few hours ago.
