buy it you'll like it.
My hair is naturally wavy so most of the time I let it air dry and I walk around looking like I am wearing a nest on my head. Straightening my hair goes a long way in avoiding that look. The straightener that I usually use is manufactured by a popular company starts with an r and cost a mere 22. I think that the differences between this more expensive brand and the one I usually use are insignificant. This styler heats quickly. So does the cheaper model. This styler straightens hair adequately. So does the cheaper model. The only differences are that the ghd classic 1 inch styler has a longer cord with a built in gfci device and remote test reset unit and is about an inch and a half longer which puts your hand further from the heat. In summary this model and brand of hair straightener heats up and straightens no better than a much cheaper model but does seem safer from an electrical heat standpoint. Except maybe for professionals I'm not sure that the significant cost difference over 100 is worth the additional safety features.
3rd September 1665: Up, and put on my coloured silk suit, very fine, and my new periwig, bought a good while since, but darst not wear it because the plague was in Westminster when I bought it. And it is a wonder what will be the fashion after the plague is done as to periwigs, for nobody will dare to buy any haire for fear of the infection? That it had been cut off the heads of people dead of the plague.
