Title: Don't buy this
Review: I have already lost an entire tank of CO2. This is very poor quality. The valves have to align pointing exactly at the out tubes to not audibly leak. I am pretty sure they still leak a little anyway. I had to remove the gas in port and put more silicone plumbers tape on the threads to fix that leak. I regret buying this. For the amount of CO2 you will lose, it is worth getting a good quality dual or tri-regulator.
