Review on XPOWER A-2 Airrow Pro: Efficient Electric Computer Duster and Air Pump Blower - Blue by Darryl Blumenthal

If you really want to clean the inside of your PC and power supply unit, that just doesn't help. The air pressure is pretty good, but it just isn't focused enough like compressed air to get rid of the dust that builds up inside a computer. It perfectly cleans the surface layer, but the dust that was there longer remains and you have to use a can of air to remove it, even with nozzles. The air coming out of this device is also very hot. very fast and not at all what I'm looking for in a computer/electronics vacuum. The device is VERY loud, louder than our household vacuum cleaner. A supplier that Amazon connected me to even though they didn't say anything about it on the purchase or checkout pages. Maybe I'll buy an air mattress so I have something to use it for.
