Perfect little bubble part! Had imagined him much smaller and I am very impressed by the size - about 14x14 cm, which is very passable and looks at my desk really good. While all plastic and the walk is a little warped, but the fan is still safely and securely - even on small rubber feet has been thought! The on / off switch on the back is handy.
The airflow is amazing, the portion blows pretty for its size and very importantly, we hear almost nothing. Well, who sits in a soundproof room, will probably hear something, but at work in the office (like mine) or normal sonicated environment he is inaudible.
And the price? So whom 7 Euro 85 are too expensive ...
