In the bedroom, still too loud, Level 1 a little too much, otherwise the best I ever had.

Actually, the best fan I've ever had,
quick and easy installation, all very stable and of high quality,
nothing rattles, it is very quiet, you can hear only the air flow,
the motor and the swivel mechanism are processed so great that they operate silently.

I use it in the office and 20m² in 20m² Bedroom,
in the office, he is perfect, it is enough loose Stage 1, Stage 3 Turbo is really very strong,
I use only when no one is in the room, cool rapidly down the air.

In the bedroom he's still a bit too loud (to my mind)
This is due to air flowing through the rotor and the front grille,
the grid I have now removed and the volume has been significantly reduced,
Unfortunately, the security ;-)

It is important to put the fan on a stable surface is,
otherwise it may lead to vibration noises.

It would be nice even one step lower or hold a smaller device (4 wing) choose.

It is a pity that the manufacturers offer no continuous regulation.
