I was not expecting to be impressed by this air duster. I've tried several at a similar (or slightly lower) price point, and I figured that you just can't get air blowing out of something small like this with sufficient velocity to dislodge dust. However, I stand corrected! This duster works very well. It's not quite on the level of canned compressed air, by any means. But it's also completely hassle-free, and, of course, rather more environmentally friendly.

I use compressed air to clean electronics and photographic film for scanning. This will work really well for cleaning keyboards and other peripherals (there's a brush attachment as well as a couple of other styles), it'll mostly work for cleaning camera gear and PC internals. Stubborn dust may not 100% dislodge, but I can certainly save most of my canned compressed air for only the most stubborn stuff. Camera sensors and photographic film, the jury is still out: I suspect that dust can move its way through the blower and I could end up depositing new dust particles instead of removing them. Time will tell on that front. All in all, I'm happy with the functionality that this provides.
