Well unpacked, amazed, already in love. No way, when I turned on the part I knew going back!
A whirring like here have already written some, that sounds like a car running the auxiliary fan is better to cool the engine.
AEG I would have expected more. It would really have been a dream machine. So he goes back.
Now I know not whether I have just caught only one of the bad models and again to start a trial, or whether some simply perceive the sound as not disturbing and thought it was part of the wind noise.
If someone were to leave a comment, that would be great :)
