It works perfect!! I have medium course wavy / curly hair and it leaves my hair soft, silky and smoothly straightened. I've been using the Infiniti pro for years and my old one had short in the cord. I haven't had any luck in replacing it until now. I had been ordering Infiniti pro 1" online from different places and would get one that didn't look like this one and plates were cheap made with some kind of silver coating. And it burnt my hair. I was so lucky to have found this one it's exactly what I wanted and is perfection!! I'm so happy!!
