These are the only hair straighteners I have ever used. I remember when I got my first job I was so excited to buy my first pair of ghd's (I have since updated 3 times) . And they have never failed me! They straighten my hair nicely without leaving lines down my hair and they don't pull at all.
I have never been able to master doing ghd curls on myself but they are so easy to do on others. One tip spray your hair with hair spray before and after curling to make sure it holds as best as it can.
I love how it turns its self off with in 30mins. The amount of times that iv done my hair and gone out afterwards just to remember I haven't turned my straightener off, but that's no problem when it will do it its self.
I have used a few different straightners over the years, GHD you can't go past. Heats instantly, glides through hair, and straight in two sweeps. I can literally straighten my hair in 4 minutes. There is no going back once you have used GHD's.
Tips: Use a protective heat spray first and a mist spray once you have straightened to catch flyaways.
