Review on Cordless Compressed Air Duster for Computers and Keyboards, Keyboard Air Spray Cleaner, Dust Cleaner Compressed Air for Car, Air Cleaning Tool, Cordless Rechargeable Air Duster with 6000mAh Battery and 10W Fast Charging by Marcos Fiallo

I bought this device hoping for good things. For starters, I charged overnight (at least 8 hours) before using. The next day I used it 4-5 times as a test, about 5 seconds each time for the keyboard etc. The next day it wouldn't turn on at all. Recharged, 4-5 hours. That's when I found out that when fully used, it only lasted about 30-60 seconds before the battery died. I tried charging overnight for a week and saw no change - the battery could only explode for about 30-60 seconds before dying. So I threw it in the trash - a waste of about $80. Back to air canisters for those hard to reach places on the keyboard etc (where a rag can't reach).
