Review on U.P. Aqua CO2 Regulator with Dual Gauges by Jenn Simmons

Excellent product. Works well and looks pretty bright. The only issue I really had was that the connector's threads were a bit loose and I had a hard time tightening it with an Allen wrench. Even with the teflon tape, I still had a leak between the fitting and the regulator until I finally found a regular wrench and tightened it almost to the point where threads snapped. To play around with loosening and tightening connections on the regulator again, all you have to do is screw the new tank into the adapter. And one more thing, there are no guidelines so make sure you do your research before collecting. You want the on/off valve to be 100% on when you put on a new tank, or you're going to have no time with it and make sure you screw it in quickly, or you're going to lose a lot of CO2.
