1) Safety cut-off. Your GHD MK4 Black IV Styler will automatically shut itself off after 30 minutes, minimising the risk of damage if you forget to switch them off in the morning.
2) Dual-voltage. Use your hair straighteners in Europe, Australia or even the USA. Or perhaps just in your bedroom.
3) Shiver protection. If you accidentally leave your GHD IV Styler in a cold place, the microprocessor will not start heating up the plates until the temperature of the unit is high enough to avoid damage being caused by condensation that may have formed inside your GHD IV Styler.
4) The GHD IV Styler comes complete with a DVD demonstration of the GHD Styler functions and teaches you how to straighten, curl and style your hair the way your hairdresser does!
