I ordered this compressor for service with my PCP Air Rifle. After receiving the compressor, I set it up and inserted the plug fitting onto the discharge of the fill hose and started the pump against a deadhead. I had set the auto off to 3000psi and after 25 seconds the compressor stopped at 3000psi. Next was filling my air rifle air receiver which was at 1850psi, hooked up the compressor and turned it on and began topping off the air rifle receiver. My auto stop was set to 3650 which took a measly four and half minutes to fill. Outstanding fill time. The controls are easy and straight forward, I really like the digital temperature gage so I can monitor the compressor temperature easily. All in all, I really like the compressor, it is reasonably quiet, fills fast and it is easy to use.
