This is a great flat iron. It self adjusts the temperature to fit the needs of your hair.
I've used these straighter for years and love them. They get so hot and I can do my thick hair in a few minutes. Plus they are salon level so have the extra long cord. However it sounds like you need to buy from the ghd website. I did and it arrived pretty fast about a week I think you know its genuine and the price is the same at 150.
This safety feature ensures that you never have to worry about forgetting to turn off your hair straightener, especially when you were in a hurry to get going. Flat irons with this feature automatically turns off after 60 to 80 minutes of run time. The Infiniti Pro by Conair Tourmaline Ceramic Flat Iron, for example, shuts down after 60 minutes so you never have to worry that you’re coming back to a burned down house just because you forgot that your flat iron was still on.
I read lots of different reviews about these straighteners and a lot said these aren't genuine. They are definitely ghds just professional ones which means they are lighter. They are exactly the same ones at my hair dressers. I'm happy.
