This is a disappointment compared to the old staples ones. After two sprays it is already freezing and the tip of the straw always freezes and blows off. Waste of money.
I had an old laptop that hadn't been used regularly. It heated up very fast. I was told that it may be due to a dirty fan or an old battery. I changed out the battery and I used this product to clean the cooling fan. I did the best that I could -- I could not remove the fan from the laptop; so I had to blow the compressed air through the vent holes. It seems to have worked. The laptop still heats up but not as much as previously.
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.
