Canned Air Duster for Computer - Disposable Keyboard Cleaner Cleaning Duster for Electronics, 4PCS(10oz)

I am an artist and I make jewelry from Jewelers' Brass. This product is indispensable to my drying my neck collars after polishing, as this requires a strong, prolonged spray. I have tried spraying for 10-second intervals and it performs beautifully. It would have sprayed longer, but I did not want to press my luck.Other canned air products have either failed miserably and will not spray, before freezing up or they will spray for several seconds and stop.I used to wonder how one could rate canned air.

The cans I received froze up quickly while using them (like 7 seconds) and didn’t have very good pressure. I’ve used worse but I would consider these low to mid quality

Just a lot easier having it delivered and product works greats.

Great value
