Anyone using Airwrap~

I was so excited to receive the Airwrap as a gift yesterday that I took out the long barrel and tried winding it. It didn't work at first, but after trying two or three times, it started winding automatically.

But maybe because my hair was completely dry, or maybe the temperature control, or the washing time was off, but after about an hour, it went back to being straight again. Please give me some styling tips.
