I've used a Chi for the past year and it did an adequate job. I mostly want to CHI Hair make my already straight, fine hair look polished and stay that way during the day. The Chi always made my hair look fine when I left the house, but it was usually stringy and separated within an hour or two.I decided to try a more professional flat iron, and honestly wasn't going to pay $ 100.00 for one, so this was the next best thing. I haven't used a chi, but I really think this works great. It heats up fast, leaves my hair shiny and smooth and really does make my hair super straight. My hair is course, curly and frizzy usually and this just makes my hair healthier looking.So, protect your investment and keep your flat irons clean and spiffy so they CHI Flat Iron can continue to give you sleek sexy straight hair.
