I bought this new about a year ago, and doubt I sprayed more than 25 gals. through it. Works like a charm with the Smart-Control feature. I have a smaller sprayer, GX 17, that I use most of the time on fine finish work so I dont need this one anymore. Comes with 50 stock BlueMax hose and contractors gun, and unused RACX517 tip and holder. Complete with seal kit and paperwork.
