Dust-Off Compressed Gas Duster for Electronics Cleaning - 4 Pack (DPSXL4) - Perfect for Keyboard, Computer & Camera Lens Cleaning

Only 3 of the 4 cans work, the 4th wouldn't work at all. Will get a different set next time.Use this to clean electronics. Works great.When I opened the package, I noted that three out of four cans were encased in plastic. The fourth was not covered and had no spray tube. That's not a big deal, as I can reuse one of the other tubes, but I recommend inspecting the package when it arrives..Indispensable for cleaning tight, intricate items and areas. Great for cleaning the nooks and crannies of a car's dash/console.not enough pressureDeceptive Picture. This picture gives the shopper that they get a total of 16 cans. I believe the text is correct that only 4 cans come at the price advertised.
