Croc infrared hands down!!!
Also i've heard excellent things about the babybliss nano
I use a Jilbere Xtreme, which cost me $20 bucks, because it out performed my Maxiglide.
OMG I just got my FHI this weekend and straight ironed my hair for the first time in several months. That flat iron made my hair so silky, like I had a fresh relaxer. I'm 4b, thick & coarse with 8weeks new growth and my hair has that runway bounce and flow (yes I have been bouncing when I walk and taking advantage of any gust of wind I can't help it, it's that silky).
I am dreading having to cowash and lose my bounce, but I just needed to straighten it for dusting oh well
I love my GHD, I've tried the Chi and an older model of FHI (I hear the new models are amazing) but I prefer my GHD classic.
