Review on 🔋 Convenient Maddog CO2 Fill Station: Dual Valve Bottle Refill for 12oz, 16oz, 20oz Tanks by Wesley Carreras

Obviously there are serious quality control issues with this gas station as there are many positive reviews (if they are genuine) but I have one that leaks constantly when I open it the tank to fill it up. My only workaround is to unscrew that knob completely and use the fill tank pressure to open the cylinder valve. This obviously doesn't allow for full filling, but it's the only way to get at least some liquid without it seeping back. I would only recommend this to those willing to roll the dice whether their game works or not. Buyer warning!
