It is worth not a long report. The entire fan is made of thin, lightweight plastic and makes a corresponding impression, but doing what he should. On the positive side of the on / off switch on the back. And no, he is not really silent, even if the fan noise is quite uniform and monotonous, and the only way interfere in the background ... but quiet is different. Ok for the price. The counterpart of metal acts much more robust for the few euros more at a similar noise.
