Finally gave up on canned air (which I use a lot of) and got one of these.
I have this one which has been solid for me
Funny you post that, I ended up getting one as well - from one of the big power tools companies. It has their usual big rechargeable battery brick.
Along with blowing out dust from keyboards and deep, dark corners of my desk, this thing will get plenty of use blowing out dust from the blades in my floor fans throughout the house (we live in Arizona, so dust is an unavoidable P.I.T.A.)...I’m using it for a few things like cleaning difficult to access parts on a bicycle derailleur (the pulley wheels) and cleaning out the computer.
