I was first introduced to this flat iron while receiving a professional Keratin hair treatment. I was thoroughly impressed with the accuracy in which you were able to control the heat setting (you can actually set the temperature to a specific degree...up to 450 degrees). I remember inquiring as to what flat iron he was using on my hair.. The salon owner told me that it was a "Croc" - the best flat iron on the market.. And it is. My hair is fragile (color treated) and I simply get the best results from this Croc. I love it, and will never use any other flat iron, as no other can compare to this one. I mean it, it's awesome!!!
