Soda Fresh Pump & Pour Fizz Keeper Cap for 2 Liter Bottles -Black by JOKARI

I ordered this inspire of negative reviews. I was about to write a negative review, then realized the silicone seal was upside down in the gadget. For the negatives, flip it up to where the beveled edge is towards the bubble, then try it. Mine works GREAT!! Those seals are placed by hand and alot of the time are placed willy nilly.

Works faster and quieter than the pump up and down ones. Releasing the pressure takes getting use to. I'm ordering 2 more as back up. Great product! UPDATE!!: One of mine broke trying to unscrew it to place on another bottle. Went on easy but, finally, had to use pliers to remove it.

These bulbs pressurize the air in a partially used bottle of carbonated beverages, preventing loss of the carbon dioxide dissolved in the beverage from gradually leaking into the air which causes the liquid to eventually go flat. They do not prevent some loss but definitely extend the fizz duration. It is important to squeeze the bulb many times to apply enough pressure, which can be assessed by the resistance felt in the beverage containers sides when pressed by hand.

Not as effective as I thought it would be. I still end up throwing away around half a liter of soda.

Seriously great invention!! Every time we would buy a soda bottle the next day we would just through almost all of it, it wasn't good anymore! Now with this invention our 2 litter sodas last up to 3 days . So yeah 👍🤩 definitely recommend it

Soda Fresh Pump & Pour Fizz Keeper Cap does not keep the the fizz. To do this it needs to keep the pressure in the bottle high. This cap does not do that either. I have the cap on very tight, I pump it up and within minutes the pressure releases. Do not waste your money on this product.

Unless you really dig around on the description for this, it's not clear whether you're getting 1 or 2. You're led to believe 2 because of the pictures and the fact that the exact same thing that is clearly only 1 and half the price is also available. But this is still for JUST ONE. It works fine, of course if you have a 2 liter it will take a bit to pressurize but that should be this thing called "common sense". I wasn't patient enough to spend 5 minutes reading the whole description what with running 3 businesses and having 2 kids and all so I hope this saves someone else $7+

They actually work in preventing the liter bottles from going flat. I did notice there were to different prices noted: Look for the cheaper priced one.

Works well

The only thing I have found that keeps the fizz in, right down to the dregs. An excellent little gadget!

One of those rare “gimmicks” items that works as described.
