I had bought another well-known rotating hot air brush to me recently, unfortunately there was only one in this rotierene brush. This one from Rowenta has 2, which I think is really great. One just needs to be careful that you do not let to roll up tightly the hair, because then burns you look at perhaps the ears, happened to me today, but really is my own fault. However, the Cool level is not as cool as it should be eingentlich. Because the cold stage is nevertheless still very warm. But I'm still very happy with the Frisierergebnis. Have medium-length hair and I can produce beautiful waves, just the pony. the two different Rotierschnelligkeiten are great as well. The device is not that hard and you do not need to spend as much by force in order to style itself. All in all a great device, which I really can recommend.
