I watched sooo many videos before I ordered one for my daughter. She's mixed, black and white, and her hair is kinky curly but has good texture. I just knew this was gonna work and I could put down my flat iron for good. WRONG! It came in and I had her way her hair, I blow dried it out straight. Added some heat protectant silk spray I turned the 2.0 on and turned it up to 450 and got to work. I tried every technique I could think of. I stopped to go back and watch videos again. Maybe I was doing it wrong. Did I mention this was a Birthday gift for my daughter? Yeah.... Towards the end, she asked if we could just return it. It just wasn't working. She wouldn't let me take pictures. I had to get the flat iron out and start all over so that it would look right. Couldn't get to the roots. It didn't do the ends. The rest was so frizzy. I used so much of the Silk spray trying to get rid of the frizz, that her hair looked greasy the next day so that wasn't the problem. I've returned it. Now we see if they give me my money back. It cost me $14+ to ship it back.
