According Leise..alles or is in the eye of the viewer or the listener

The part selber..solide to see stable and nice.

Cable Length "normal" ... the state is really great to 3 points.

The operating range is vertically adjustable, easily.

I live in an apartment with DG windows that are slightly less than 80 cm high .... the little one is responsible for the active exchange of air, because the windows open only happens here often nothing at all. The practice looks like in the morning, window, fan on the window sill .... and Power. Works suuupperrrrrr.

Issue volume, it seems to divide the spirits:

Practical example:
The device is about 2.50 meters from me at eye level. That can never operate silently, a fan should be clear to everyone.

Level 1: Audible but not annoying. TV volume remains unchanged ..... I understand every word.

Level 3: Audible (he) .... TV must be made loud .... swirling air quantity therefore represents me and ordinary sense in proportion to the volume .... not overly. In a larger room or in further distance ie noise will not limit the quality of life of the beneficiary).

The Venti is werkeln neatly on .... is doing what he should .... I fly but not gone, not even at level 3. You just simply have to be realistic.

Conclusion, buy recommendation !!!!!
