I bought this to clean dust from my printer. If you hold the can perfectly vertical it work fine. However if you tip it slightly in any direction it blows out cold liquid propellant. So I couldn't get the job done with it.
This product is a real blow-hard. When I first pushed the button It blew my desktop (not just the computer but my whole desk) into my neighbor's back yard and he live 5 miles from me. I totally recommend it maybe hook it to your car's back bumper and save on gas!
