This is awful.It freezes up after a very short amount of time. The can actually gets frost on the outside in a matter of minutes. I would never buy it again!
Whenever I become overpowered by the smells of urban living (diesel exhaust old trash the neighbor frying fish) a few quick sprays of Staple's Slight Ethereal Air Duster brings me back to the great outdoors. I carry a can with me everywhere.
It was able to clean the dust out my PC fans but the pressure was disappointingly weak. Tried it on my keyboard and I feel like there’s still stuff between the keys. Worked well enough 3/5.
