Review on 💨 Honbay 4PCS Mini USB-Powered Cooling Fan Gooseneck Air Blower for Desktop PC Laptop Notebook Tablet - Portable & Mobile by John Faxon

These fans required assembly. They come in a bag with the fan blades removed. There are these washers that hold the motors in place. None of them were attached and one was missing. I added super glue to hold them in place. After everything is glued together it's great. Powerful engines, they pump a good amount of air. Just a little noisy. I'm not sure I would buy them again.
