Operation: 1 Star
When operating one has the feeling that the wrist is refracted. Personally, I find it easy to use failed. The acclaimed by Rowenta sensor is shown looking from the handle bar which is pressed into the housing while covering his hand. Only by the hair dryer is running. The blower and heat level are mounted on the side handle. A switch to another fan or heating stage requires the second hand.
Sound: 4 stars
The hair dryer is definitely quieter than our 2 year old Brown.
Airflow / air volume: 4 stars
The air flow at the highest level is somewhat weak. However, there is a "power button". This is necessary to hold, then exits a decent airflow.
Weight: 3 stars
The hair dryer is a little hard (subjective feelings).
