if you already own a hair iron you do not want this brush [SEP] i am a sucker for any product that claims to straighten hair against my better judgment i ordered this product and sure enough it does not work well the metal base heats up quick but the way the brush is designed it cannot get at the roots of the hair so the first of the hair shaft remains pouffy while the rest of the hair gets more or less straight a hair iron works much more efficiently learn from my mistake and save your money you do not need this product
