Venilator good for fresh air

Have been looking for the office a small and quiet fan. The regulation of the fan via a resistor and 4 USB hubs were not decisive for me.
The air movement is pleasant and not too strong, so you can let the Venti run all day without getting dry eyes. Have the fan approx 0.5m placed away from me and the draft is absolutely pleasant. Best of all, however, this is absolutely inaudible fan even at full speed and thus is totally Office Suitable. But you should already be clear about that can not produce a "storm" these fan !!!!

***** ***** BUY recommendation

EDIT 17/10/2012:
The Venti still being quiet and to my complete satisfaction. The wings are not indeed protected by mesh or the like, but even if you accidentally touch the blades, they will not be broken. Can only recommend this product.
