Great for really curly and thick hair. And perfect for a lot and long hair becuase of the size. It last long, but with only a once or twice per month use. It is lightweight and doesn't tire your arm as much when doing long, thick hair. The shine in your hair is surreal and leaves your hair super straight for days. Effectiveness It leaves your hair straight and shiny, and does not cause as much heat damage as other flat irons. Durability It lasted me 2 years using it 1 or 2 times per month.
