This is my third Chi flat iron. It's plain, and has no heat controls or bells and whistles, but what it can do that many can't is straighten my frizzy, curly hair, with no damage. Make sure you get someone to show you and use a good hair prep spray, and don't leave the iron on your hair too long. Use very small sections.
I paid the premium price for this flat iron to get the results I've had from my stylist. However, my hair did not look any better than my cheaper iron, and didn't stay straight and smooth after a long day (my hair only has a natural wave). The main reason I'm disappointed is because this iron does not have an optional heat setting or auto shut off! I feel like it has damaged my hair, and my counter is now burned because I forgot to shut it off in the morning before work.
I love my original CHI, but I gave it to my granddaughter when her flat iron died. I was really nervous purchasing a new one, because I had been told that the second generation CHI wasn't as reliable as the first. So far so good, the old one and the new one work great.
This product was one of the worst I have ever used. The straightener heats up quickly but it becomes too hot and I had to continuously turn it off to let it cool down (just to be able to hold it). I burned myself twice and my hair would not slide through the plates and kept getting stuck. I have always heard CHI was the best so I was extremely disappointed with this product. BEWARE - there is no way to adjust the temperature and it does not have an automatic shut off.
I absolutely LOVE this product. I have thick frizzy hair and have been straightening for years. This is the only straightener I have ever used that will really keep my hair frizz free--even in the rain or out dancing and sweating. For the first time ever, I can wear my hair down and go out without worrying I'll look like a poodle at the end of the night. Only downside is it does damage your hair if you don't use a heat protectant, but this is to be expected with any straightener. 10/10 would recommend.
