Watch Dust Blower Air Pump Cleaner Tool - Yellow

Pros: i got this for use with my PC. a can of compressed air can cost up to $8 a can where i am, thats rather expensive. i can use this to clean out my keyboard, albeit it doesnt have the same air pressure as a compressed air can

Cons: nothing i can think off

Other: it has more uses than what it was intened for, what other uses can you think of?

Pros: Nice machined metal nozzle.
Bulb has a nice micro-texture finish.
Great for dusting off optics and other small items.

Cons: The vent check valve on the flat of the bulb is open by default and slow to close. If the bulb is squeezed lightly, it may not close at all, resulting in air blowing out the valve as well as the nozzle. If a plastic ball were used in the valve (rather than metal), it would probably function better.

Other: It works well and feels like it should last. The price seems perfectly reasonable.
