Well if you are looking for a pretty good dust remover for your electronics it does pretty good. When I first god it, well it started to have a foaming like look on the stuff, but I realized i was too close to my computer but after I got alittle distance from the computer the dust remover worked good. Just kinda keep a few inches away so it you will not have a chance to mess up something that you should not mess up.
When I got use to using it, well it worked just fine and it will remove from just more than your computer, also like radio's, gaming equipment, and all other kinds of electronics. Do not spray on open wires or live wires you may catch something on fire at anytime, it has never happened to me, but it can if you do not know what your doing.
