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.
Dual-Zone Technology: You will have heard of Tri-Zone Technology if you own a ghd Platinum Styler, so think of Dual-Zone Technology as its little sister. Instead of three heated regions, this styler features two, one towards the tip of the styler and another closer to the base. This essentially means the straightener has better control over the way it heats your hair, instead of over-delivering in one area and lacking in another. Think quicker styling and a more uniform look in terms of sleekness and smoothness.
I purchased this ghd after a hairdresser friend used hers on my hair. I couldn't believe how well it worked so I purchased the same model. I have curly frizzy hair and this straightener actually makes my hair shiny and even holds my hair straight if my hair gets wet in the rain. I use a hair straightening treatment on my hair before I use the ghd as you should with any straightener and this keeps my hair from becoming brittle. I have lovely comments about my hair since using it. It feels very soft and is healthy. I can adjust the heat setting so it does not get too hot. It is very quick to heat up and beeps when it is ready unlike others I have tried .It is so simple and quick to use. Because it is the wider ghd I can do my hair in less than five minutes. I have long hair past my shoulders. Very happy with this one.
As far as we’re concerned, this is the best hair straightener we’ve tried. Not only does it heat up in record time (only 30 seconds until it hits 365°F), it’s also been lauded for its frizz fighting capabilities—as mentioned above, a must down South. What’s more, it lasts. One editor’s trusty Classic Styler is still going strong after 4 years of almost daily use.  
BEWARE of sellers with LOW FEEDBACK! Ask sellers questions about the 22 things I have pointed out above. If they do not answer, don't buy! If they make excuses, don't buy! Also, some buyers who have been ripped off are trying to resell their GHD's to cut their losses. Watch for things like "I got it as a gift" or "I recently cut my hair". One of the seller's I purchased from was supposed to be shipping out of Georgia but he really shipped from China. Don't believe everything you read about a seller's information. They can lie.
