Review on ELUTENG Adjustable Computer Compatible Playstation by Mark Clark

I used it for extra airflow in a box I made to convert laptop to desktop. It's not the main fan (and it's not big enough to be used that way). They are small and easy to use. The shifter has a solid feel and positive click for each of the 3 speeds. There could be a bit more cabling between the controller and the fans, but that's very reasonable. They are very quiet and move a good amount of air for their size.
