Review on NuPow 8-Inch Quiet Small Table Fan - USB Powered, Portable Foldaway Design, Adjustable 540-Degree Angle, 3 Speeds, Wall Mountable - Mini Room Personal Fan for Home Bedroom Office - Includes 5ft Cable (Black) by Mayra Castillo

I bought a fan because of the design. It is lightweight and easy to carry and use. It can be smoothly tilted to any angle. It comes with a small manual that contains basic instructions. There are no instructions on how to operate the fan, although it may seem intuitive. You may need to test it first: just press or hold the power button (on the back) for a little longer to change the speed setting. To turn off from the lowest speed, you need to switch to the highest speed or quickly press the power button twice. If you want to turn it back on after turning it off, you may need to wait a bit for the fan to start working again. Otherwise I'm satisfied.
