Now I have the brush now for 4 weeks use. And lo and behold, even I, untrained, much time and energy in styling techniques to invest unwilling come prima cope with the round brush.
It is lightweight and fits comfortably in your hand. The compartments of games is very easy with the retractable, red style. The hair can be easily screw with the brush while blow-drying with a single hand. Even my big and rather straight hair can be so easily put something in motion. The lengths are doing beautifully smooth and - as I have the impression - even shinier.
So far, the brush lies always just slightly unscrew again without tangling or tweet. Also no hair have been torn out by the edge so far.
I get along very well with this brush, much better than a normal Fönbürste or using a round brush from the drugstore, with which I live at loggerheads since year. The size 33/50 mm is optimal for me (hair length up to the shoulder blades). The second size 53/75 mm, which I bought at the same time, to me is not so. The diameter is too big for me, I collect hair repeatedly from the game including with a, also I do not get enough momentum wound.
