Update 17.8.2012:
There are now a little more like two weeks have passed since the purchase, and I am still convinced of the positive concept of this device. In the video I had the 1st stage when it comes to power, something "denounced". Actually you can feel the air flow even two or three meters out yet clear, but not too strong, which in combination with the panning mode and the "natural wind breeze" program has proven to be a small blessing for me. Because permanently suspend a strong airflow, will eventually simply unpleasant. Grade look at the TV, the device is bearable and it quietly and from entgegegen to a cool breeze blowing.
Presumably, the builders have even can reduce the 1st stage at 30% capacity, then the breeze effect would also be noticeable and the equipment would again quiet a lot, so that you could really use it to fall asleep. But that really is a very personal opinion, everyone feels so different :)
What I have noticed so:
The swivel mechanism produces a faint, but clearly perceptible "whirring" and once it fully swings to the right, the fan is running short minimally louder. Probably due to construction. Even now is not really disturbing and if you actually endure garnicht, panning is yes at any time suppressible.
Also with me it is - very rarely - in front:
The side panels come sometimes to oscillate and generate a vibrating sound. When I lift the fan short or touch the sides, but it disappears again. This occurred especially in the early days of purchase, and now only very rarely. It is quite possible that the pedestal is not completely flat on the floor stand (power cables underneath) and thus it came to this effect.
In spite of this, great device. Get me to buy it again.
