Review on Upgrade Your Draft Beer Kegerator With The TerraBloom CO2 Keg Pressure Regulator - Dual Gauge Heavy Duty Unit With Safety Features by Nonito Shin

Appears to be well made, I have tested it for leak down. I did this by turning on, using it. Then I close valve and let it sit for 30 minutes, rechecked and the same pressure shown on the gauge. I have not checked it at longer timed intervals . However after a day its lost all pressure.Not sure if this is acceptable or normal. Make sure you have all connections TIGHT, but don't go CRAZY tight!The ball is moving well and I hope its calibrated correctly. I have no way to tell.Otherwise seems well made and solid! I would buy again and will since my tank collection is growing!
