This is the best straightener I've ever used. Absolutely worth what I spent on it. I use it as a curler as well
Each flat iron has its own 15-digit code on hologram which can be verified at GHD website. - One 1" ghd flat iron with cap. Smoother gold plates glide effortlessly through the hair to make straightening on all hair types and lengths even quicker and easier, while their contoured edges help to create perfect curls and waves, all with a high shine, salon-style finish.
I bought this as a replacement for a 2008 ghd and whatever they have to change the models since I absolutely love it my hair comes out shiny and smooth and it takes me half the time to straighten my wavy hair as it did before. It heats up in 10 seconds.it also has not had any residue build up on it I've had it about 6 months whereas I used to have to clean my old straightener periodically.
It is authentic . I read some review that said it isn't authentic but this review was in 2013 maybe in this year ghd didn't work in us but it has changed. Great purchase . Also you can use it in europe
wife luvs em ghds are the best in her opinion.
