I guess 15 hours of hard use. I had a habit of pumping to 4800 PSI trying to get all I could out of my 90 CI bottle, not anymore. I only pump to 4400 PSI now.
But over all I like my lil chain pump and how much more I can shoot. I say go for It If you can work on things and have good mechanical skills. Keep in mind its cheap and at some point in time she will need to be worked on.
