Rated 5 out of 5★ by MysteryDetectives I've tried several of these dust canisters. Most were sold in two packs for $11 or $12 dollars. Ultra Duster was about $5 for a single can and when I used it, I found it was the best one yet. First off, this single can has lasted about as long as two cans from the other brands. Also, the other brands say you need to spray for a few seconds to let the chemicals release, I found with Ultra Duster I could begin spraying my keyboard and computer immediately, no chemicals, just air. I'm buying this product from now on. 02/28/2013
Rated 1 out of 5★ by Tara8595 Product sprayed liquid Even when held upright, this product sprayed some kind of chemical which quickly evaporated, but still, I don't want that all over the inside of my pc. I just wanted air, not a bunch of white crud everywhere. 08/31/2012
