Review on Avatool Cordless Air Duster and Keyboard Cleaner - 2-in-1 Dust Blower with Vacuum Function, 6000mAh Battery, 10W Fast Charging, Powerful 36000 RPM - Replaces Compressed Air Can by Seth Singh

Cheaper to Buy Harbor Freight Pancake Air Compressor that works 10 times better than this thing. For convenience, it's still better to use canned compressed air. I had a great test of this unit, an old keyboard that I used 12+ hours a day for about 5 years left it for parts. The cleaning power of this unit is a joke compared to a cheap compressor or convenient canned air. This would be a regular $20 tool and not the 60+ it now lists if you want to spend more time cleaning something that would take half the time with a better tool.
