The curling brush fits comfortably in your hand and is easy. The buttons are large and easy to move all what is important for older people. The brush heads can be replaced easily by the "open" are set on the brush head slider and then you can pull the brush upward from the device. Since there is no latching or turning fummeliges where something could break. The enclosed instructions explain everything to give even the hang of quickly itself. See the hair after blow-drying with the brush very good. Certainly not as perfect as the hairdresser made, but very close! Important: The small brush has no ceramic coating. This is not really clear on the pictures and the description. The small brush is designed for short hair that go around to the chin. The large brush is perfect for long, at least shoulder-length hair. The hair dryer is not too loud, at least not louder than other Föngeräte. I was the noise at most disturbed when I had a strand of hair wound dirket next to the ear. And to the horror scenarios from the Internet, I can say: The Fönluft is neither too hot, nor the long hair tangled, nor is pulled by force to them, yet you lose control of the rotational movement or a hair sucks! The device is absolutely harmless and the rotary motion is gentle.
