Absolute rubbish.Condenses almost immediately (and conducts electricity), has no straw, does not sustain pressure for more than 5 seconds, is highly flammable AND costs more than double the price of other equivalent products.Took a couple of hours (mostly drying time) and a quarter of a can just to clean the dust out of a GPU Card.

Don’t use cleaning PS4 or any electronics for that matter. It’s wet and now my internals of my ps4 are drenched! I have to leave it open to hopefully dry out and fingers crossed there’s no damage. Instant refund for me. TERRIBLE PRODUCT

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.

I've used air dusters brought from Super Cheap before that had a thin tube connected to the nozzle that let me blow dust out of keyboards. This product does not have a tube and as a result it is very hard to properly clean computer keyboards, especially on laptops. It becomes an exercise in frustration tilting the can and laptop to try get air in between the keys.
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.
I see a lot of reviews from people who aren't using this product correctly. Every single air duster product like this, that uses a compressed gas like difluoroethane, will come with the same drawbacks.The gas expands rapidly at room temperature, but then the canister quickly cools during use leading to condensation and a weaker blast. It should therefore be used in short blasts, no longer than a second. I typically do three short blasts before shaking the can. I don't know why the manufacturer advises us against shaking the can. It's an effective way of bringing it back to an operable temperature. I recommend shaking the can. Come at me, WD40. I can repeat this blow/shake cycle about 7 times before I need to let the can sit for a few minutes. By then my job is ... MoreI see a lot of reviews from people who aren't using this product correctly.

I can repeat this blow/shake cycle about 7 times before I need to let the can sit for a few minutes. By then my job is usually done, or I just grab another can from the shelf. I have many because I buy it in enormous quantities when I find it in stock. It's just that good.Regardless of temperature, you cannot angle the nozzle up or down, or you will get sputters of liquid gas and condensation. You will need to position the thing you're cleaning so the it's directly in front of the horizontally positioned nozzle. If you're cleaning something that doesn't allow for this, that's a bummer, but what you're looking for is an air compressor, not an air duster like this.The one complaint I can agree with is that the nozzle isn't very focusssed, and would benefit from a straw, but have you used the ones that DO have a straw? You press the button and it gets blasted right out. Perhaps the solution is a straw that's actually part of the cap as a single piece of plastic, with the option to break it off. Honestly it's not a huge issue as anything you can't dust away from a 15cm distance probably requires a cleaning method other than air dusting anyway. You cannot air dust the grime under your keyboard keycaps. Trust me. The bond formed by hair, grease, dust, skin particles and saliva is unmatched by any epoxy resin.I've tried plenty of similar products to this one. Most run out absurdly quickly, condense too easily, or just never have that much pressure to begin with. WD40 is the best one I've used, and now it's the only one I buy, but you have to remember that it's kind of an annoying, temperamental product to use no matter how well made it is.
