Less damaging and less "flat"ness than any other flat iron
The Ferrum Styler is truly unlike any other flat iron I’ve tried! One plate is tourmaline-coated ceramic; the other, the one you put on the outer side of the strand you’re ironing, is non-heated(!) and covered in soft fabric. The latter is meant to let hair breathe while also causing less damage. What I noticed most is that it heats up fast (140–450 degrees) and it doesn’t make my hair flat. It smoothes it and makes it softer and better-looking, yes, but also voluminous. The plates are beveled so that if you can easily do a little flip at the ends for movement. I don’t think I’ll ever switch to another iron after trying this one. Pricey, yes, but in line with other professional hair tools and well worth it.
