My daughter says she has the Chi with the red fuzzy stuff on it (I think it's the turbo?). As you know, there are several choices of width, depending on how long your hair is. BTW she always gets annoyed at those people selling flat irons from the carts at Lenox. They always flag her down, as if her hair could possibly get any straighter after using the Chi.
I like the FHI flat irons because that's what my stylist uses. My hair gets wavy, especially when it's humid outside, and the FHI really straightens it out to give it that funky, Asian look.
Except at the beach. I can spend forever straightening my hair prior to going out to dinner, and before we even get the group photo taken, my hair will frizz up. So my hair always looks like hell when I'm at the beach.

I used to have it long enough to French-braid at the beach, but it's so thin that it looked like hell all of the time *except* when I was at the beach.
