Cordless Compressed Air Dusters for Computer Keyboard, Portable High-Pressure Electric Air Duster Cleaner Blower for Electronics, Replaces Air Cans

Works great! I've had it for a few days now and I've been blowing dust out off all sorts of stuff I couldn't get to before, tops of cupboards, fan blades, little crevices in window sills, etc.. my main concern was getting the dust out of my computer. I've been having heating issues lately and I blew all the dust out of the case, and nooks and crannies I couldn't get to. I was going from 50°c idle to around 35°c. Massive improvement! It doesn't take long at all to charge. Plenty of power out of this little thing. One negative is the cheap materials it's made out of. It's cheap plastic, so it will break easily if dropped or mis handled. The on/off trigger feels a little recessed and kinda feels like if I push too hard on it, that it will break it. It's a little loud. Not really a big issue. Think of it as a hand held anti-vaccuum . The attachments fit well enough.  It does have a good battery life and takes no time to charge. I'm not sure I would have spent $70 on it. I got it on sale for $50 and it still seems a little steep considering the same technology is out there for cheaper. Example being a hair drier.

(1) Very Loud! (2) Works best on high pressure setting. (3) Would be helpful to have a longer nozzle with a smaller hole at the end. More powerful than canned air but the longer, smaller nozzle on canned air is much better for fine cleaning. If there is not an small nozzle available or an attachment for the current one I will probably just make one. (4) VERY useful for tasks other than cleaning electronics equipment. We have 2; one in the house
