The fan has two speeds, which are easy to adjust with a knob on the Rückeite. In the slow stage is a humming heard that perceive me or colleagues as not disturbing. Partial Taking the oblivious.
The zwiete, fast stage but then heard, but still in a mass, d ass I can represent. But unlike many large table fans, he is silent.
The connection is via a USB cable, which is almost 2 m also long enough for me.
In the center and the lettering PEARL is then printed as it is seen in some pictures.
Overall, you get what you pay for. It's a small relief for the summer but does not replace a large fan. Nevertheless, I find him well and have used it a lot. Hence a buy recommendation, if one thinks of such a small purchase.
a total of only 4 stars because the noise in the high speed operation can be heard yet.
