Well designed CO2 dual stage/dual bubbler regulator
Well designed and well made regulator in this price range. 1st unit had issues with maintaining 2nd stage (low-pressure side) pressures over 30 PSI, but the outstanding team at Glass Aqua walked me through a very thorough troubleshooting process to identify and resolve the problem. Highly recommend the company, Glass Aqua, for any of your equipment needs, they know their gear!
