I got my Readyair compressor, it was packaged so no damage would occur, unboxed it and attached everything the way they said to without any problems it was very straight forward.
It came with the recommended default settings installed except for the amount of air which I set at 3000.
First fill on a empty tank on my Gauntlet from zero to 300psi took eight minutes, i forgot to cock the rifle so I had to refill it again and it only took 6 minutes this time. Topped my Kratos off from around 1900 to 3000 and it took only 4 minutes and the cooling fan never kicked on. The fan stayed on for several minutes when filling the gauntlet but shut down when cool. The piston housing never got hot enough that you couldn't grab ahold of it, fan does it's job. My only gripe is I wish the hose was longer and maybe a right angle connector. Haven't tried it on DC yet just house current. Happy with the result, very well made machine.
