Oo! Ok well PS said she has the chi, and believe me those are really good, most of my friends have them! I used to have one as well, for about 2 years, but somehow it died on me. I just invested in a sedu and it's amazing! I belive it's the ceramic/tourmaline (1 inch). You can get different sizes, like a 1 1/2 etc. Find out how long her hair is, mine's just to the middle of my back and the 1 inch is great.
