My 2014 Dell desktop computer was intermittently crashing (a sudden complete shutdown). Each time the computer was restarted it failed to load some important files. I thought I was going to have to buy a new computer. I bought this Air Duster to clean dust from the computer components. After cleaning the computer is working fine!
I would recommend it but I don't know if it's supposed to have a extension so that you can get down in the cracks mine did not have it would have been good to have it
Worked well at blowing off the dust on computer fans/parts/keyboard. Can gets cold if you spray if for a longer period of time so just let it sit for a bit. And then go back at it.
I had never used this brand until buying it at Staples. It did the job as expected on my keyboard. It is also useful for tight corners in drawers and shelves. I would recommend it.
