I bought one of these last year and they are brilliant. Use it when making my light boxes, cleaning out computers, also even good for cleaning optics, as all it blows is air, no propellants etc. It lasts 15 mins on a full charge, there are literally dozens of uses I have found for this piece of kit.

Check out the video on the site gives one an idea of what it can be used for. I have no affiliation with this site, it just happens to be where I purchased it.
