Just delivered today and tried it for the first time. It looks like cheap Chinese junk (port freight) at a price meant for sale to the masses. While there isn't much to know about using this compressor, the instructions are only printed on the packaging itself. No other manual was included and the instructions printed on the box were written by someone who doesn't speak English very well. It's a dead sale, where does that come from? Not sure if this portable air compressor will last long. I think time will tell. Once made in the USA with higher quality materials and craftsmanship, such devices were designed to be a quality, reliable product that would last. This air compressor may or may not do the work for you, but either way it feels really cheap. Update 02/25/2018 After only owning it for three or four days, I took this compressor for the second time today. to inflate the tires on my wife's Honda Civic. The compressor is completely dead. Couldn't get it to work. Dead. Dead. Dead. Good thing we were on our own road and not in the middle of nowhere with a flat tyre. This is indeed a piece of Chinese junk as I suspected. I am returning this POS Revain and will purchase another compressor. Hopefully a compressor that will last more than once. Avoid. Don't waste your money on this unreliable Chinese junk.
