Like new only four and a half to 5 months old 2 gallon 135 PSI one and a quarter horsepower quiet ultra quiet series Fortress air compressor with two quick disconnects and adjustable regulator tank pressure and Outlet pressure gauges and the ultra quiet muffler exhaust which is why I wanted it so it wouldn't keep my neighbors up and I went to use it and it worked for one moment and once it built pressure and it got down 75 or 80 it didn't go back pressure like it should and I don't have the receipt I don't even have the card that was used to buy it anymore cuz I had to replace my card so I believe that it just needs a sensor for the back pressure that builds up in the manifolds for like 13 bucks but I'm not sure I am selling a bunch of stuff cuz I need money so if that's all it is then you'll really score on this deal. I also have various air pneumatic tools and adapters and hoses ask me about those as well if you need any
