It functions good and can't beat it for the money. The pressure gauge threw me off a first because my compressor was reading at the stop point of 110 psi and I couldn't open the regulator reach that pressure. I checked the pressure with a gauge after the regulator and had the full 110 psi but the gauge on the unit only showed 75 psi. Sadly the port for the gauge is too small for my 1/4" gauge fitting.
