Review on Compact 4 Inch USB Desk Fan: Powerful Airflow, Quiet Operation - Perfect for Cooling Desktops at Office or Home by Chris Russell

This fan produces a lot of airflow with little noise, but when you turn off the power it resets so you have to turn it back on with the button on the back. It doesn't start at the speed you last left it at. I bought a USB switch which would turn it off easily as the back button you use to change the speed is not in a comfortable position for me. Unfortunately, when I turn it off with the switch, I still have to press the button on the back to turn it off. EDIT: I've had it for 18 months and it's still going strong.
