I worked in the hair industry for a while so I've used a lot of high end flat irons and I got to say, this one did not impress me at all. I'd never used a GHD before this btw (none of the stylists I know have one) but I ended up ordering the GHD classic styler--which btw seems to be the same as the "IV styler"--instead of the CHI Turbo due to the fact that at the time, the GHD was on sale and basically the same price yet it offered more versatility (the turbo has a velvet cover so you can't use it to curl).
This is an expensive straightener, but it's worth every penny! I've had mine now for over a year, and I know I'll have it for many years to come. The iron itself is black and gold. I have long, thick, straight hair, but it gets a little wavy underneath if I let it air dry. If I blow dry it, it gets a little poofy and I use this to give it a more smooth, sleek look. It takes a couple passes of going over my hair before it's completely straight, but with cheaper ones it takes longer. It doesn't take too long to do all of my hair. It heats up super fast, and if I'm in a hurry and forget to turn it off, it turns off by itself after thirty minutes. I have dropped it a few times, and it's still going strong. I recommend this for everyone.
Best flat iron, 2 year warranty when bought from the website. Don’t have to adjust any heat settings you just flip the switch on. Smooths out all hair textures hair really well! And if you forget to turn it off the heat element shuts off and the flat iron beeps at you until you manually push the switch to off which is amazing since lots of us forget to turn off our flat iron after use.
For me, the first and still very best of all ceramic stylers [and my dad is a hairdresser too]. It heats up fast, cools down relatively fast, works wonderfully and lasts a long time. In 11 years, I've bought two such stylers. The first one eventually died after 6 years of daily use, rarely skipping a day, while my second one is still going strong. I have no reason to recommend any other styler but this one. My hair is long and very fine.
