This is my second chi. The first one was an original model and I dropped it on tile after a couple years of use, worked great before that! This chi gets my hair straight and shiny better than the old one, however it pulls my hair. I have hair to my collar bone, so its not that my hair is too long. I have to be extremely careful how I move it through my hair to avoid hair pulling. Even when I am careful it still seems to catch on to my hair somewhere. I like the chi's straightening abilities, but can do without it hurting me!
