My grandson used it to get the dust out of the fan in his laptop. It worked well and the fan functioned properly and was able to keep the computer from overheating.
The compressed air product works great -- the air pressure level is high and it cleans dust/debris from computer equipment quickly. Two problems: 1. It's pretty expensive probably 2-3X the cost of what you could find elsewhere; and 2. the plastic needle/tube keeps popping out of the hole in the nozzle so you have to use 2 hands to use this product or you will be retrieving the nozzle every few seconds... very annoying!
What can I say? It’s compressed air. I normally can buy a 2pack for less than I paid for a single can. Nothing wrong with the product except for the price.
