CHI is the absolute best flat iron you could buy! I have thick, coarse hair and this flat iron works wonders on it. No other flat iron can compair. My stlylist has a CHI and she convinced me to buy one (one of the best decisions I've ever made). Oh and fyi, no the CHI does not have a temp. gauge, however the heat applied to the hair intensifies as you compress the iron. The harder you squeeze, the hotter it gets!
