Meanwhile, I have this small fan three times in action. 2x 1x home and in the office, where colleagues are increasingly envious with the current weather conditions. The unit runs quietly (office-friendly) and can be activated at the back with a toggle switch. The cable is in my opinion too short to connect one standing on the table fan with a PC (Tower), standing on the ground below ... at least then you have only very limited design options in terms of location. I operate the device once to a USB hub, once connected to a USB port on a monitor stand, and once with a USB extension ... everything works splendidly. The oldest unit I have purchased a few weeks ago and it is 5 days a week for about 4-5 hours in use. So far, nothing has changed at the quiet operating noise. Therefore, I like to give my buy recommendation.
