I got one of these items a while ago. It was basically the price of 3 cans of compressed air and those cans don't seem to last long. I can't say I dust my house with it, but I probably should use it more. It does do a good job of dusting the electronics though. #dust #CompressedAir #ElectricDuster https://www.theverge.com/23551860/electric-air-duster-cleaning-pc-compressed-air
