I don't have much to compare it to but a hand pump. Seems to work well. Pumps my FX Streamline from 120bar to 230 bar in about 3.5 minutes. I was debating between the Crosman and one of the Yong Heng compressors. Being able to use the Airgun Nation 25% off at Crosman is what persuaded me. Also the Crosman does not need to be lubricated or have an external coolant system. It has a built in fan & cools with air. After 2 weeks of use I decided to upgrade the moisture filter to one of the Gold Tuxing filters with dessicant beads. Switching from a springer to a PCP .... all I can say is "WOW" !!! The Streamline shoots sub 1/2" groups at 50yds all day long with JSB 18gr
