I tested for several years Irons "cheaper" (Gama, Babyliss) - lais there I decided to pass the course by offering me a HDG. What minquiétais as this was the authenticity of the device (because of numerous articles on fake GHD products that are dangerous limit).
After having received (in the time expected and with a nice little note from vendor), I immediately checked its authenticity on the site that records the real GHD appliances and reports fake. Mine was well recorded and since this is happiness.
It super heats quickly - in 15 seconds no more. Smooth my hair (curly enough) in a single pass and does not dry them as my old irons. The only downside - it is not that obvious to do curls with this iron (as I have seen in many movies) but I'm working.
