I used this product to help clean out dirt/debris from an Xbox 360 controller that was malfunctioning. Worked great! I plan to use it next on my keyboard. Good product.
It is a good thing that I read the reviews for this product because it doesn't take long for the can to freeze up. Which means you don't get the full content of the compressed air to clean your computer. I bought 3 cans which amounted to about a full can. The store associate upon check-out should also remind customers to use gloves and wrap can in towel to avoid freezer burn.
