7 21 14 I purchased this flat iron on may 25 2013. I've used this product every day since then with no issues. Also the styler is not a fake and I was able to register it on ghd's website with no problem. I only buy products that are ship and sold from amazon.com only maybe that is why so many people have received fakes I'm not sure. I have course thick hair and this flat iron has been wonderful. The plates are hot but doesn't damage my hair or the ends. I would recommend this flat iron.
First, there are the temperature settings. Obviously, different hair requires a different heat level. The thicker your hair is, the higher level of heat you should apply to straighten it. I highly recommend you to read the instructions which usually say what temperature you should select for your particular hair type. This may vary a little bit from one flat iron to another. The general rule here is the less heat you apply, the better your hair condition will be. And always use a heat protectant, regardless of your hair type.
A replacement as loved the first ghd straightener I bought.
