Review on YYjop Cordless Air Duster: Powerful Electric Blower Cleaner with 15000mAH Battery & 45000 RPM for Computer Cleaning by Micheal Chaplain

If you are environmentally conscious and don't want to worry about countless air tanks then this is a good alternative for you. It has its own quirks but is powerful enough to blow dust off most areas like your computer and keyboard. I don't like how long it takes to actually start blowing air or controls. You need to turn on the can and then press the power button again for high speed. I would have preferred a dial or switch to control fan speed. Would also have preferred some sort of trigger instead of a button to turn the fan on. It lasted a few months while I owned it and did a lot of wonders in dusting my computer case. Otherwise it gets the job done, albeit VERY loudly, and does it well.
