My Opolar air duster from a previous ozb deal has been on the fritz for a long while only working for 2 seconds when fully charged, but works fine if left plugged in. I've been meaning to diagnose it for a while but there's not much information on the internet and when searching for a replacement I found this one that is not only an air duster but a vacuum also. For $25 I think it's potentially a really good deal, apart from the included USB to 9v barrel jack charger (I would have much rather USBC or micro USB so can use any cable and not a hard to replace charger if something goes wrong with it).

These things are really good for cleaning dust out of electronics and the vacuum might make it useful for around the house too.

Is it strong enough to not need air cans ever again? π If it does 3/4 of the job of the can, I'll snap one up.
Edit: First review says it works just as well as canned air, but is even better when you put on the long nose attachment (atleast for keyboard cleaning).
Double edit: I can't add it to cart..
