Too small to be much good for most household uses, such as inflating tires, blowing dust off items, etc. The tank is so small you get a burst of air for what seems like 10-20 seconds, and then the tank is empty and it must kick on to refill. If you want strong air pressure, you will have to wait for the tank to refill, which isn't long, but significantly longer than the blow time. So, there winds up being a lot more waiting than working. Lightweight, compact, quiet, and seems to be decent quality, though.
