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

It works shake then put on a flat surface or you'll get liquid in your devise although the liquid didn't damage my phone so stand the can and use the straw provided as the bend or angle as not many things can you usefully spray with a static flat in its base tin But that said it cleared my phone (blew air post the liquid).my phone charges now it was protesting before I bought this stuff I bought the two tins I can't imagine I'd need two so. I and you might have one you can give to a family member it's worth buying two as it's only £1 or £2

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.

Not a particularly strong flow of air

Good product I use a lot of it
