I'm absolutely in love with my GHD. I've been wanting to buy one for a few years now but was a bit hesitant paying $240 (Australian) so when i seen them on sale i thought i would bite the bullet! I will never buy another brand again (I've used remington and babyliss) it heats up super quick, glides through the hair like butter and takes much less time as with previous straightners i've had to go over the same strand a few times and it left my hair frizzy and needing heaps of product to smooth it down! Definetly worth the money, has 2 years warranty and barely need to use any products except hot iron spray and a tiny amount of moroccan oil. The product curls my hair perfectly and would have got the one with wider plates for my thick long hair but wanted to be able to use it to curl. A must buy for those that use a straightener often.
For curling, place a section of hair between the plates closest to the scalp, clamp the plates, and turn styler through 180 degrees while holding the end of the strand. Pull styler through the hair slowly, always maintaining the 180 degree turn--it helps to slightly tip the nose of the styler downward, careful not to let the hair fall out. It also helps to pull the strand forward when trying to curl hair at the back of the head.
