For those who think GHD is the same as about 7 or 8 years ago it's not. They're all made in China now and the quality is nothing like the ones that they use to have.
If you're looking for a good quality straightener look for Glampalm, which is made by the same Korean company that made GHD before they changed to Chinese manufacturers.
