I got this GHD as a present and I think this is as good as the normal mark 4. I really like the glossy look and case which comes with it. It makes a perfect present!! Normally I don't read the literature which comes with products but the dvd which comes with these is very useful.
I think I disagree with Stephanie here, this GHD curls and straightens as well as other normal GHDs. It gives very nice non-frizzy curls. I have very long, thick and curly hair . I have always used GHD for straightening, and every time they give perfect results.
I love it and would highly recommend it as well.
