Review on Hromee Air Compressor Filter Regulator Combo Kit - 1/2 Inch With Pressure Gauge, Semi-Auto Drain, Water & Oil Trap Separator, And Bracket For Improved Performance And Efficiency by Julian Locklear

I installed this between my compressor and hose reel. Installation was very easy and trouble free thanks to the metal (NOT plastic) body. Everything feels well made except the cut off valve. The cut off valve does feel cheap but it does not leak so it is doing its job. Pressure adjustment is very easy and quick. The locking function is great, Because now that it is set i do not plan to change it. The gauge seems to be right in line with the gauge on the tank, but I will test occasionally to make sure it stays reading correctly. I would recommend this to anyone looking.
