The device comes in the simple Kunsttoffausführung but makes a fairly stable first impression, which is also confirmed in use. He is stable and the vibrations are low! The air flow is sufficient for a good working at your desk without a list and all the leaves around the ears fly (tested at 30 degrees in the booth and at a distance of up to 1.5 m ca.1m to the device). The volume is in a pleasant area and will not interfere. The unit has made an a / - switch which I think is quite handy because it does not directly losbläst plug in. the only drawback (if at all) is that you can not adjust the rotation speed and thus the air flow (which is for the price but also can not wait)
For the price is the unit highly recommended. My new ally against heat in the workplace.
