The product came as advertised. Donna spent about 45 minutes on the phone with me explaining how to dismantle and rebuild using these parts which went exactly as described. Donna is very helpful. The parts arrived by Canada Post in a bout 2 days and I'm back up and running. I'd recommend Maple Airbrush Supplies to anyone who uses airbrush equipment. I've passed on this recommendation to the other 18 members of our Plastic Scale Model Club here in the Fraser Valley.
