I bought a four-pack of the NXT 10oz Air Duster. Specifically I purchased it at this time to blast dust out of the filters in my new Romba and Shark stick-vacuum but I also use it for cleaning my computer hi-fi and ham radio equipment. It works as it should. No complaints.
I work at the recieving end of a trucking company and nothing cleans our grimey keyboards handhelds and radios better than this stuff. With covid and greasy hands our company has been grateful that staples employees suggested this cleaner!
