I use the straightener a few weeks now and am generally satisfied. In use with an ordinary heat protection spray (I use Got 2 B guardian angels) are smoothed my hair much better than my old Braun straighteners (after all the times test winner at Stiftung Warentest was). However, the results are better in professional hairdressing treatment. If I even I have the next day a few curls, so I have to re-smoothed. A plus: the hair no longer fly so much after smoothing with the GHD. Minus point: the price still seems outrageous.
