This is the coolest product with numerous uses. Besides the obvious electronics cleaning instead of wasting money on countless cans of store bought air you can use it for car detailing, blowing yourdelf off after mowing the lawn, sweeping/blowing out shop floors or blowing off porches and sidewalkes. It last about quite a while, around 15 minutes, on a single charge and blows really hard. I highly recommend this and the uses for it just keep popping up. Great little device!!!
