Review on 🍺 MRbrew Stainless Carbonation Cap - Pack of 2, Ball Lock Type with 5/16" Barb, Counter Pressure Bottle Filling Cap including 4 Additional O-Rings, Ideal for Most Home Brew Soda & Beer Carbonation Systems by Belinda Phelps

Edit - I chose to remove the extra star because the bar is larger than advertised. I recently received a high quality flow control circuit breaker machined from a single piece of stainless steel. Unfortunately, this liquid release is not suitable as the pin diameter is approximately 15.78mm. The listing says 0.6 inch which is just 15.24mm. It's only half a millimeter, but it does matter when my decoupler's ID is 15.65mm, which means it won't fit in this rack. Tighter tolerances may not be available. Working from home I have found that I drink a lot of soda so I have decided to switch from cans to 2 liter bottles. The problem is that 2 liters runs out, before i can drink it all I already have a paintball tank CO2 system for a beer mug so I decided to give it a try. The lids appear to be well made, although I'd actually prefer a shape other than round or maybe some texture to help with screwing them on and off. When working properly, they do an excellent job of maintaining and even increasing carbonation while loading CO2. However, I had to deduct a star because of the washer, which feels a bit small and therefore prone to falling out. and fall to the floor or counter. sometimes falls out of position when the cap is on the bottle causing CO2 to leak out. After the cap leaks and you remove it, the washer will be in the neck of the bottle, not the top.
