Set of 1 Alloy Steel Co2 & Compress Air Regulator Output Pressure 0-300psi

Your browser does not support HTML5 video.  The gauge does not line up correctly on pressure settings, the pressure will not stay on the pressure I set it on, and the co2 gas leaks out of the knob you turn to set the pressure. Update...I have received a full refund so thank you. They would like the part back but after double checking the gauge it still leaks. I tried my HPA tank on it thinking maybe it just froze up from co2 and it might work with just plain old high pressure air. Still the very same outcome. So it would cost me $17 dollars to mail a piece of junk back to China...not going to happen!
