Review on Battery-operated Air Duster: Rechargeable & Reusable for Computer Cleaning, Keyboard Cleaning, Portable Compressed Air | 10W Fast Charging | 6000mAh Cordless | No Gas Required by Aaron Wagner

God! This thing almost knocked my mouse off the table, it's very powerful! It is not triggered via the SECOND button, but about 1.5 seconds after the trigger is held down. I like this feature so it doesn't accidentally activate. She is really powerful! It's also noisy, but let's face it, if we're cleaning our electronics and we're not home, what does it matter. It will activate for a few seconds or minutes (depending on your use case) and then you're done. If you're looking to save money on canned air, this is for you!
