Cons
Con It only has one speed when operated via USB cable
When the fan is operating via USB cable, it only has one speed. This is not ideal for those who find the default speed too low, and require stronger air flow.
Con The fan only works when plugged in via USB cable
The fan can only be operated in 3.9 feet radius of the USB port (that is the length of the cable), as it does not work without it.

This desk fan only has one speed, which is not ideal in a case of extremely hot weather or room temperature. The fan will not provide alternative speed settings to suit everybody's needs.
