Check Out The 02 Hurricane Computer Duster- We Offer Free Shipping and a 30 Day Money Back Guarantee!

I bought this to blow dust and dog hair out of computers and it is pretty much useless. This is not a replacement for canned air. You can blow harder with just your mouth. I would definitely buy a small hobby compressor (which costs the exact same amount of money) before this. Yeah it may be a bit larger but at least it would work. As it is now I have a 80 dollar piece of junk that I'm struggling to figure out what to do with. The construction feels fine and it is small, it just doesn't move enough air...

We bought this for one of our college campuses to try out before we purchased for our other campuses. The users said it doesn't have enough power like a canned air duster has. Also, the straw nozzle is too big. The thin straw that a canned air duster has gives out much more force.

I would not compare this to regular canned air, but it does a good job. It's stronger than a blow dryer but not as strong as canned air. The straws do not increase the velocity, they only limit the radius of the stream, so I prefer not to use them. I found this great for silk plants, small collectibles like dolls and stuffed animals, and larger debris like leaves.The three major pluses are the lack of toxic chemicals, the ability to recharge instead of repurchase, and the fact that it doesn't freeze up like canned air after 30 seconds of useThe company over promises when comparing it to canned air as apples to apples, and I think they do themselves a disservice in doing so. But overall the pluses outweigh the minuses and I would recommend it based on the lack of toxic chemicals alone.

I bought this product as a renewable environment-friendly replacement for compressed air to use in cleaning out computer parts and other tiny nooks and crannies. The mobile battery design is very convenient, and this is what I use more frequently, but for heavier duty blowing I pull out my  Metro Vacuum ED500 DataVac 500-Watt 0.75-HP Electric Duster 120 volt  instead. The DataVac has stronger air flow and is cheaper and louder, so may be a better value for your money, although it must be plugged into the wall to use.

I was really expecting more, I guess. It doesn't seem as powerful as it should be and is noisier than my vacuum. It does work but not as well as canned air.

Biggest False advertising of all time. The tube that the air blows through is too big and doesn't stream line the air to be strong enough. Canned air works so much better than this. Please don't purchase. It's a waste of money.

I bought this item to help clean-up my electronic devices. I was not impressed by the output of this device. I returned it as it did not hold up to it's claimed.

It does what it says it will do.It does not have the same amount of thrust as the can of chemical air, but it does the job.It is more environmentally friendly and I do use it frequently.I will never used canned air again.
