I bought this to clean dust from my printer. If you hold the can perfectly vertical it work fine. However if you tip it slightly in any direction it blows out cold liquid propellant. So I couldn't get the job done with it.
The NXT brand of compressed air cans are like most. They do their job and pretty well. Can seems to be constructed fairly well. The only thing is that the straw can occasionally come loose. I grab these on good deals when I need them and I get my money's worth.
Wonderful product. Working from home requires a lot more maintenance and cleaning of your computer/printer 🖨. Dust off does the job well. Great cleaning product for when you have to work from home.
