I used my nieces flat iron and it is one the chi flat irons, it worked so good. I thought I just had to have one, but I saw how much they cost and I couldn't see myself paying the money for it, because I'm cheap. I saw this Belson Pro flat iron in the store and decided it was a nice price and I would give it a try. It worked nicely, Just the same as the chi. So, on a scale of 1 to 10, I would give it a 10, its gets really hot!
