This system is expertly designed and fully functional. It has undergone a recent self-test and is in excellent cosmetic condition. Though we could not conduct a comprehensive test, there are no visible signs of damage upon inspection.
Please note that the P-920 may show an "80 warning Pump Overpressure" on the screen, and the attached picture shows a broken holding clip on P-950. Due to our limited testing capabilities, this unit is being sold as-is.
