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 Mike Hamelin

1. Does not regulate pressure at all. It gives you maximum pressure no matter where you set the valve.2. The ball valve leaks. If you turn it off the air still leaks through. Had to use one of my own, old ball valves.3. The air pressure it shows is more than 20 pounds off the actual pressure. I checked this with two different gauges.This is totally worthless. Since it took me so long to get it out of the package and install it, I cannot return it. So in to the garbage it goes.
