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 me, the first and still very best of all ceramic stylers [and my dad is a hairdresser too]. It heats up fast, cools down relatively fast, works wonderfully and lasts a long time. In 11 years, I've bought two such stylers. The first one eventually died after 6 years of daily use, rarely skipping a day, while my second one is still going strong. I have no reason to recommend any other styler but this one. My hair is long and very fine.
