Review on Adjustable Pressure Relief Control Devices by Sean Patel

It's ok but cheap. Works most of the time, but settings are drifting. The scale is completely inaccurate. Use a pressure gauge to set the relief pressure. Mine fell apart while zeroing it due to a crappy pinch to hold the screw mechanism. Probably wouldn't buy it again. Update 11/25/19: I downgraded this device because it does not remain sealed. It constantly leaks until the keg drops to zero. It was shelved while I tried several other cheap ones with the same leak problem. I went back to it and tried cleaning the needle valve and valve seat. Cotton swab brought out metal filings. But that still hasn't solved the problem. Will not recommend or buy again.
