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).
Against the ghd Platinum Styler: On the other hand, the Platinum Styler features more sensors and heaters than the new ghd Gold. This essentially means it will heat the hair quicker, and is a little safer in terms of heat delivery, too. Six sensors and heaters work to deliver optimal heat to the hair, instinctively adjusting to give you a transformative experience. Where this is the top-of-the-range choice, the ghd Gold Professional Styler sits perfectly in the middle, a great mix of affordability and professional quality.
GHD Classic Styler, from the name itself, you can deduce that this simple yet versatile device was made to style and straighten. Armed with a rounded barrel and advanced ceramic heaters, you can curl, flip, tease, wave, and straighten any hair type and texture easily without damaging your hair’s external surface. The infra-red heat technology infused within the plates also releases more negative ions than other products so your hair’s natural oils and luster are retained despite repeated exposure to maximum heat.
