It works - however -1. draws too much current from my old usb 1.0 (dell inspiron) jack and sometimes the computer gives warnings.2. makes about as much noise as my laptop fan.3. it can only be used on a desktop, not on your lap.4. workmanship is below average.Also, the unit draws air from the top where computer is - not sure if this is more effective than blowing to the computer.
