In the process of upgrading a lap top I heard some unexplained noise. My technician suggested that a "compressed air cleaning" could help. Your product solved the problem.
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!
