Just as the title says it’s a can of compressed air. The only difference between this and other brands is price. I don’t think there is anything special to rave about that separates it from other cans of compressed air. I mean it blows. It does its intended purpose. Blow air to remove dust from hard to reach areas of your electronic components without static build-up. 1 can did a decent job of blowing out dust bunnies from my mid-tower sized pc. Note: only blows out the loose dust from cableways fans VRM’s etc. for dust build-up you will need a anti-static clean dry cloth or rubbing alcohol or mineral solution and q-tips since these solutions are generally non-conductive of electricity and rubbing alcohol evaporates.
