Using this fan is a breeze. First, clip it securely to your desktop or any suitable surface. Then, plug the USB cord into a power source like your laptop or a power bank. To adjust the wind speed, simply use the mechanical controls to switch between the two available gears. When it comes to maintenance, keep the fan clean by gently wiping the blades and the net cover with a soft, dry cloth. Avoid using harsh chemicals or getting the fan wet. Also, make sure to keep it in a safe place and don't let it fall, as it doesn't have a fall - stop function. That's all you need to know to enjoy the cool breeze from your fan!
