Pros: it's metal..

Cons: no speed control, the speed control is used by tightening the center screw/knob there is no electronic speed control..

Other Thoughts: not what i thought it would be. the speed is based on the usb electric output..

Pros: cool design and colors. nice fan size

Cons: very slow air movement, big fan, but for a 140mm fan, moved air very slow. i could barely feel air blow at me from 2 feet away.

The fan control was described as most people would intend fan control to be, but was not the case when i received this device. there is no way to make the fan go faster or slower. you can only adjust the oscillating plastic cover from spinning fast or slow. very stupid design.

Pros: Looks great, decent airflow.

Cons: It either has no fan speed control or I couldn't find it, and I'm an I.T. hardware tech.

Expected more for the size in terms of airflow

Way overpriced. Should be at least $15

Usb Cord is short
