This thing is what I've wanted forever sick of compressed air cans they are so expensive and honestly don't really work that great for long at all this thing packs a punch way more powerful than a can and comes with more attachments that you need keyboard putty as a bonus little brushes that in those nooks n crannys that really help loosen the dust before you blast it away I don't usually get this excited for an Amazon purchase but this was above and beyond what I expected if you have a pc and keyboard that you like to keep prestine this is for you it also would blast away anything you really throw at it 5 stars very happy with my purchase.
