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

Basically if you need to clean some dusty places (computers) - just take this instead of one time use. Many of the single-use cans are $10 each, and after a few of them you end up paying for that higher-end refillable can! To top it off, it's better for the environment to just get this reusable style. Aside from doing the same thing, it comes with a brush that allows you to really get in and brush off the dust. I've used this to get into hard to reach or delicate places - especially for computers and fans where you can't get your fingers in.
