Air Duster Can Compressed Air Spray Can Dust Cleaner PC, Keyboard, Electronic Devices & Car Cleaning Protect, 2 x 400ml, Packaging May Vary

They are effective for a few seconds of use but then they get too cold to touch and the air doesnt come out properly until you wait for them to warm up again. Other than that, gets rid of dust effectively. Still seems to have lots of air left and very powerful. Good value.

Very pleased with this twin-pack of air duster cans. I used them to clear debris from my laptop keyboard, various printers and the inside of my tower PC and they did the job very well. The spray was strong enough to dislodge dust and crumbs without me having to struggle and there's plenty in both cans so I feel I've got great value. One thing to note: it's quite cold when it sprays so you need to keep it moving across the area you're cleaning, which I did and it worked without fuss. The nozzles are decent and I didn't experience any of the issues others mention about them clogging or misaligning. If you're after a reliable budget air-duster to maintain your tech gear then this set is definitely worth considering.

It does what it says on the tin, t's compressed air. Good value

Not a particularly strong flow of air

In my experience, compressed air canisters tend to offer similar performance across different brands. This particular one works well, delivering consistent pressure that clears out trapped dust and debris. Occasionally, it does release a small amount of liquid propellant instead of gas. While this hasn’t been an issue for me, it could be an issue when used near temperature-sensitive components or delicate electronics. It should also be noted in case anyone doesn't know that if the can is used upside down, it will release only the liquid propellant. This liquid is extremely cold, typically between -20°C and -40°C, and can cause frostbite-like burns on contact with skin. For safety and best results, the can should always be used upright. Overall, this is a reliable and effective option for general-purpose cleaning, especially for removing dust from tight or hard-to-reach areas.
