Works well, if used in short bursts to avoid surface frosting thus extra caution is needed when using near glass. Recommend use of safety glasses when clearing gritty surfaces.

Just awful. No tube nozzle, doesn't blow that well. Makes everything freeze up instantly. DO NOT BUY

I purchased this during the week to clean keyboards and Dyson Vacuum filter. What a dud, inconsistent blast of air, liquid propellant comes out at same time sticking any dust to the filter. Wont work when not level. A complete waste of $19-00. Back to Jaycar to buy something that will do the job. Have learnt my lesson.

I bought this product because I needed an air duster. My needs were simple. Push button on can and a reasonable blast of air should come out. Nope. Push, blast lasting fraction of a second, push, nothing, wait, push, weak hiss, wait, brief blast. The can is definitely full. It gets icy so the propellant is definitely still there. There is no visible damage on the can or spray mechanism. It's an $18 dud.
Bought this to clean out my computer parts, my Playstation plus some drills. As long as you shake the can well, use in short bursts (up to 1 second each time) it works well and does what it is supposed to. I can only assume that the other users aren't doing this. If the can is feeling a little cold from over-use wait till it goes, shake properly and use again. I did get quite a bit of use out of it. As long as you can get up close and personal with what you need to spray, it does what it is intended to do.Follow the instructions and it works.
I bought this to clean my keyboard. It does get some of the crumbs out but as soon as you tilt the can away from it being upright condensation from the pressurised gas builds up. not great for electronics. There's no nozzle/straw to direct the air so you have to get pretty close to get to where you need it leading to the condensation problem again. I'll keep using it because I've got it but I wouldn't buy it again and I wouldn't recommend it to other people. If you shook the can you can get better air pressure but it made it more liable for condensation.
Terrible! Bought this to blow out the computer. Has very little pressure, barely moved the dust and certainly didn''t get the dust out. Blows massive amounts of condensation as well, luckily I started on the fans on theoutside of the case because if I had of used it on the motherbpard etc I might as well have sprayed water on it there was that much when spraying! Horrible product that will kill electronics while keeping the dust safe and sound!
I bought this to clean out my computer and dust other components. It works perfectly...for all of about 5 seconds of sustained spraying. After that the trigger is hard to press, and a pathetic little hiss comes out of the can rendering it useless. After an extended delay it returns to its great little 5 seconds of power, but when I use this I don't want to be waiting around for longer than I am actually using it. The older 5 star review really confuses me, seeing as you aren't actually supposed to shake these things. This may just be standard for aerosol duster cans but I definitely won't waste my money on another one of these.
Regret buy, I wasted my hard earned 19.99$. I lost faith in this company, while marketing a product they should clearly mention the usage of it. I could blow dust with my mouth 100 more powerful that this piece of junk and yes; I did the same. Very very weak pressure. Please keep away from this crap. The philosophy of WD40 is BAD, sorry; very very bad, they are SCAMMERS; what else should I say. PLEASE KEEP AWAY
Absolutely useless and a complete waste of money. Used it on my PS5 and instantly condensation formed on top of the PS5. Can't use for mire then 5 seconds before condensation occurs. Waste of $20.
