Excellent at cleaning computer fans but gets really cold after 20 sprays
Pros: I bought the Fellowes 99790 Air Duster a few days ago because my HP laptop overheats. I've had my laptop for 3 years, so I know it's the fan since it has gotten louder over the years. I saw online that the best way to clean a laptop fan is to take it apart and then blast air to clean the fan. But actually, it's not necessary to take apart your laptop. You can just use this Air Duster to clean the fan. This product does indeed come with that long straw that you see pictured at the nozzle (I don't know why others are complaining that it doesn't come with it). The straw is scotch taped to the side of the can so it isn't bent during shipping. So for my laptop, all I do is stick the straw as close to my laptop fan as possible and then I pull the trigger (like a gun). The more you pull in the trigger, the more air blows out. I pulled on as much as possible when cleaning my laptop fan. I suggest you apply the air to every single hole that leads to your laptop fan, and you can easily see the dust fly out of the vents.
Cons: After each spray of the can, the can gets colder and colder. After like 30 sprays (approximately 1 minute), the can will be like ice-cold to the point of you not being able to touch it since it's like keeping your hand on an ice cube. Also, since the can is cold, it like freezes the air inside, so air won't come out anymore. It's ok though because after like 10 minutes, the can will go back to room temperature (thereby unfreezing the air) and you can use it again, and spray for another minute. This is not a big deal since a minute is plenty of time to clean out your laptop fan unless you are cleaning more than one laptop at a time.

Do you need a review?
Dont know how to review this. just the cheapest air duster i found. good sized can. Has perfect pressure for clearing out my keyboards and even worked well on my tv and consoles. i also took apart my pc and cleaned it out as well. Just make sure you spray in bursts. dont hold it down and just spray for more than a few secs because the can will get cold and can potentially damage electronics you might be spraying like motherboards etc. small bursts and if the can gets cold while youre spraying just wait a few seconds before continuing =)
Other than that i see no need for you paying a lot of money for compressed air. this worked just fine =)

They spray air
By P. Dynan
Some folks are going to get faulty one, but mine are fine. Good sized can. Also has a biterant agent, so maybe my family can break our long addiction to huffing compressed air.
