Review on EasyGo Product Compucleaner 2.0 – Electric High Compressed Air Duster – Computer Cleaner Blower - Keyboard Cleaner – Electronic Devices & Laptop Cleaner - Replaces Compressed Air Cans (Black) by Francisco Holmes

I'm not sure what kind of "hairdryer" the reviewer who gave the negative rating has, but if it's as powerful as this thing, I think he/ she has very little hair left have been in the computer repair business since the mid 80's. I probably spent thousands on air tanks and a few hundred on an industrial air compressor for my old computer shop. But NONE of these articles compare to it. That has a lot of power. Enough to REALLY clean computers, fans, graphics cards, etc. Everything looks brand new and dust free. Even compressed air didn't bring me such results. it will not blow and shoot at your components. As always, these little straws appear to be for compressed air. I cannot recommend this device enough. Just buy it. You will not regret it.
