Query: not for coarse hair!!!

I have had many inexpensive flatirons over the past few years and kept hearing raves about this one. I finally splurged on a birthday present for myself and I wish I had saved my money. I will start by saying that I am caucasian but I have very coarse, thick, wavy hair. I can get my hair straight with this but it takes more time(I have to go over and over each section and do smaller sections at a time) than my less expensive one... So I have gone back to useing it. I do still use the CHI for touch ups since it does heat up very fast.
