With the hair dryer I was initially very pleased. Powerful airflow is not too loud, well in hand. Unfortunately, after a few months had the blower output noticeably, with the result that the now much reduced amount of air was too hot and the wires began to glow inside the hair dryer. Now have returned the device. When I use the reviews of Bosch appliances so look at me here, I note that in this brand now skepticism is appropriate. And that is a potential security risk brings with Bosch into the house. Too bad.
