Review on 🍾 FERRODAY Stainless Steel Carbonation Cap for Effortless Soda, Beer, and Water Bottle Filling by Kimberly Brown

I really liked this cap. I have to report that there was a slight learning curve. I mainly use the cap on 1 liter CO2 Smartwater bottles at around 40psi. At first I tried screwing the cap on too tightly, and it's possible to screw it on so tightly that the vinyl seal inside folds up and pops into the water bottle's neck instead of resting on the top of the lip. Then the lid leaks. After doing this a few times, I unscrewed the lid first to make contact and then some more to get a good seal and everything was perfect. I left it in the fridge on top of an open, partially used and sealed soda water bottle and came back from vacation a week later and the bottle still had pressure when the cap was removed and the water was still soda. I also just unscrewed and removed the small filler tube from the side of the bottle for easier cleaning and not needed. I rarely purify it unless I'm carbonated with something other than filtered water. I had no problems with the o-ring after using it for 3 months.
