Canless AirSystem O2 Hurricane Industrial Unit - 200mph Airflow - Equivalent to 25 Cans Per Charge - UK & EU Edition with Universal Charger.

Used continuously for 3 days while packing for a move and only charged once. It has been invaluable for everything from dusty books, fabrics, to delicate small collectables and game cartridges.It is odorless, pure air flow that leaves no residue as there are no added chemicals during propulsion. Works perfectly and safely for computer parts as well.Now the negative key points:1) I have very sensitive hearing to the point I can even hear some dog whistles. When this thing powers up there is a incredible high pitch whine that hurts my ears. So simply if you got pets, please think of them when using this device. It aint funny to chase them with it just cause they back away as is often the source of most vine/youtube, so called, funny pet videos. I actually use earplugs when using it when packing due to the pain.2)As pointed out in early reviews this does come with a UK plug and a few nozzles. However the nozzles themselves are too broad, and a more focused point would of be invaluable for specific cleaning into hard to reach places. By no means is this a weak device in comparison to Canned air counterparts, it just can be overwhelming on specific cleans. A good way of thinking is like using a leaf blower to blow a lamp shade. It can be highly chaotic to control when you want to accomplish something delicate.3)Also due to the broad nozzle I find with some stuff like my books covers and figures, the majority of the larger dust is blown away, but the smaller stuff remains due to insufficient power/control, which i then simply use a dust cloth to remove.Overall if the product sorted the noise issue, came with more focused nozzles and possibly a way to control the power output instead of on/off, the product would be near perfect for all uses I could throw at it. The next test is lifespan so hopefully I can return to this review a year odd later once it stops functioning, preferably longer :)

Really disappointing bit of kit.We bought this and also the mains powered alternative which was half the price of this one and there is no comparison this has far far less oomph!My son's PC was at the "turning itself off for no reason" stage - this rechargable one cleared away some fluff but didnt seem to do much at all but then the mains one displaced a massive cloud of dust+++ and the PC has been fine since.This was about as powerful as a compressed air can thats already been used a few times. If you are clearing away clumps of fluff you can see then its fine, but it was not good enough to get the dust out of a CPU heatsync.This is the 200mph version - I think they do better versions now anyway.We did not manage to compare this with the third option on Amazon which is another mains powered one thats about the same price as this one but I'd be interested to know if the expensive mains one is any better than the cheaper mains one.There are 4 options in this market that we could find1. This one - 2.5/52. The mains one thats the same price as this one - untested.3. Compressed air cans (I've used them a lot) 4/5 initially and then rapidly dropping to 0/5 when you have to buy a new one. Also they get cold and seem create moisture in the PC unless the can is brand new.4. The mains powered one that is half the price of this one - 5/5 and did exactly what we needed it to do even after this one failed.

I essentially brought this product because I often had to blow dust from my camera lenses, computer keyboards etc... It got really expensive using pressure gas canister, and I started searching for other alternatives on the internet and stumbled with this product (O2 Canless Air System)The first deception: it claims it can blows air at 200MPH! This is absolutely UNTRUE! The airstream barely reaches 25-30mph!The good side though: it suffices to remove dust from common areas, but for removing dust in difficult places such as the gaps between camera buttons and the surrounding bezel, you will still have to resort to the high burst of the pressurized non rechargeable canisters. The product is well built as well and is really sturdy.Overall, if the company was more 'frank' in the way they had marketed this product and if the product could deliver at least 50mph of wind, then i would have maybe given it 5 stars... This product will be more useful to blow daily dust from tables, TV screens rather than delivering precise short burst on specific spots...

I really actually hated this device. Maybe this feeling even reflects on myself as well as I had been hesitating for years to get it and always felt I missed something. The price drop pulled me over but it should have been even more a warning.The device does not compress air. It merely is a rechargeable hand-held fan; the kind your kid loves on a hot day in the park. Indeed, the battery powers what seems an internal fan. That is it.The device is noisy and besides a flow of air it doesn't do anything. Nothing useful. At least not when trying to use it as a replacement for compressed and/or compressed air. The airflow generated is without life and adding one of these pipe bits doesn't do a thing as the diameter is that of a large seize drinking straw. Or a bit larger. Far from the <1mm hole regular cans of compressed air punch their torrent through.I charged it fully. Kept trying and hoping against all odds to get something (much) more out of it but a fan of course can't replace the power of some Bar of compressed suddenly released air. If you need a rechargeable fan: get it. Otherwise stay far from it and if it is too late try not to swear at the engineers and marketing people too much. I've sent it back and Amazon dear reimbursed. Bad feeling stays.
