Powerful hairdryer, which is not too loud and hard and well in the hand. The temperature is on medium and hot set with weak or starktem airflow. At the highest level the Fönleistung is enormous, so that even my thick hair is dry in a relatively short time. With the Cold key is really cold air, the diffuser is not needed, this I can not say anything. On the whole, I am satisfied. The only thing that bugs me these Luftstrombündelungsdüse which falls every time at the slightest touch from. This is better, therefore, a point deduction!
