2 x Compressed Air Can Duster Spray - Cleaner for Cleaning & Protecting Laptop Keyboards and Electronics, Set of 2 by Leap Horse

as expected - done the job

Seems to have more liquid gas than previous brands I've used. Doesn't flow consistently, sometimes weak, sometimes strong.

Works just as you'd expect from compressed air. Nothing bad to say about it. All the reviewers saying there's a "liquid" coming out of it clearly have not used an air conditioner in their lives. This is simply a gas that is compressed to become a liquid in the can. When you spray it out, it expands and boils immediately, which takes energy, which makes the air and the can cold. Just like in an air conditioner. Also, just like in an AC unit, because the air is now cold, the water in the air condenses out. The liquid does not come from the can but from the air, and it's not a problem at all if you READ THE INSTRUCTIONS and spray form a suggested distance.

I seem to recall these air sprays were pretty effective at cleaning my keyboard, but as with these types of spray it was very easy to use too much. I find foam sprays to be better value for money at cleaning keyboards due to their better effectiveness when compared to air sprays which usually just spray the dust elsewhere. Also I fear air spray liquid might leak underneath the keyboard and cause trouble.

I have a Lenovo Ideacentre all-in-one. It's quite old now, but works well. The CPU was running at a high temp (min 75C, max 98C) - much too high and annoyingly causing the fan to make a lot of noise. I thought I'd try this product to blast out the dust that must've collected on the CPU fan making it ineffective. These all-in-ones are built like a very large laptop - very difficult to disassemble. So, I tried by blasting the outlet grill several times for about 3 secs each time. I didn't see any dust coming out, but now my machine is running at min 45C, max 59C - a huge improvement, with the added bonus of a very quiet CPU fan. Therefore, I would have to recommend this product and give it 5 stars.

I usually read a few reviews before making a purchase, on this occasion I didn't. Having purchased a new graphics card for my gaming pc I thought I would buy some tins of air to blow the dust out and then carefully vacuum the outside of the case and the easy to get to areas inside as well as giving the cooling fans a good blast and vacuum. All this does is blow cold liquid over everything, I was like WOAHHHHH WHAT THE F.....!!!! If I could give the product zero stars I would. BOS as Paul Calf would say.

It’s a little bit windy on times but only if you press the button on top. These cans have many uses like blowing birthday candles out or repositioning that fart away from you so your partner doesn’t think it’s you that released toxic fumes and blames the dog. The can does what it says on the tin.

I bought these to blow away the dust on my kids lego models and I have to say I was quite disappointed with the product. The air pressure was not that strong, and the first can didn't last long enough to do the job. I had higher expectations and so wouldn't buy this again.
