Query: Good but not as good as compressed air

It works fine and is decent at removing the loose dust. Also provides a good wrist workout. Looks good enough to be left out, unlike compressed air canisters. Comp air, though, is more forceful and gets the more clingy dust off. The rocket's nozzle tends to sway when you squeeze it. Not a full replacement for comp air. I'd only really recommend it for those who are environmentally conscious and/or budget conscious.
