Review: Worked great for my drinkmate bottle. - Bought this to refill my drinkmate tank. My small tank has the "old" style top, with the narrow pin rather than the wider flat anti-refill top. This "old style" top is supposed to be easy to fill - connect everything up, open the valve, and let the gas flow. Initially, no matter what I tried I could not get CO2 to flow into the small tank from the large one. I unhooked the big tank from my kegerator, connected this adapter, threaded the small tank onto the adapter, inverted the setup, slowly opened the valve on the big tank, and could hear it open but nothing would flow. No amount of unhooking, reconnecting, releasing pressure, slowly opening, slowly threading the small tank on with gas flowing, or any other tricks would make it work. It is almost like there wasn’t enough pressure in the big tank to depress the pin and open the valve in the top of the small tank to allow things to equalize between the two. Frustrated, I hooked the big tank back to the beer keg and threw the small bottle back into the freezer. I tried again the next day, and it worked flawlessly. I don’t think I had the small tank cold enough when I initially tried it. My big tank is kept inside the beer cooler with the keg, and that may have meant I needed an even colder small tank? Whatever the science, I hooked it up today, inverted the setup, and as soon as I cracked the valve I heard the liquid flowing. Several seconds later it stopped, and after weighing the little bottle I had a 400 gram fill. Whole process was less than 3 minutes. Be sure your small tank is FROZEN!
Review: Great - Worked perfectly to save a lot of money now I can refill my ninja thirsty canisters instead of paying 10x the amount to purchase new.

### ⭐⭐⭐⭐⭐ Great

Worked perfectly to save a lot of money now I can refill my ninja thirsty canisters instead of paying 10x the amount to purchase new.

### ⭐⭐⭐⭐⭐ Great Item! Don’t forget to take it off your tank before returning the tank!
*by P***5 on February 8, 2026*

Great item but don’t forget to take it off your tank when you return it or you’ll be over here like me buying a new one!! I initially bought a more complicated one with a hose and all but that one is not good. After I realized I lost this one I tried that one again and I am reminded why I bought this simple one. It’s great!
