Compressed Air Cleaner

Great for cleaning keyboards As I like my computer clean. I also have a "mini-vac" but it doesn't reach behind the motherboard or inside fans/heatsinks. I used these cans of air to push out the dust and use the vac to suck up the rest. Out of curiousity I decided to "sniff" the cans of air... No smell at all so you wont get a room smelling of some weird gas for two hours. The cans had lasted me for one month each and only for £6 for a can its worth it.
