DNA HAIR TOOLS Styling Comb

I bought this a few weeks ago after a demonstration and my hair has never looked better, but I just can't figure out how to use it properly. I have only tried 2 times, i never been dropped. I got rid of the box and there is some brown stains on there which is makeup but it works perfectly fine. It heats up wonderfully at all the temperature settings. Will ship without box. I bought it for $325.
