Jokari Keeper Pump and Pour Soda Bottle Cap Preserves Carbonation with Flip Top Spout for 1 to 2 Liter Plastic Bottles Reusable Fizz Saver Dishwasher Safe Carbonated Drink Lid Black

I've only had this for a week or far but I am already in love! It works awesome to keep the 2l soda fizzy. I'm a cheap old curmudgeon and buy the cheapest soda I can which means after the first glass the rest of the bottle is flat. Flat no longer that is! I chose this type over the pump as it doesn't have to be taken off to pour the soda. The bottle opening is a little more restricted and since the carbonation is still fresh I have to pour slower anyway to avoid the dreaded fizz foam My only worry is durability. So far fine and I'll update this review should that change but I am mildly concerned about the plastic latch giving up the ghost. For the price I am a satisfied customer and if I get a year out of it it will be a very worthwhile investment.

Easy, no problem at all, this my third one. Easy to clean, easy to operate, works great! Keeps the fizz pumped up and seals. Well built gadget. And a good price

These bottle cappers are great for keeping fizz in carbonated sodas. They work with standard, plastic soda bottles. If you are prone to arthritis in your hands, you may find you have difficulty with them though. On the off occasion when my hands are swollen and stiff, I find that I have to pump these up by wedging them between a counter top and the heel of my hand. They do take a bit of pumping, and the soda will not retain all of its initial pep. Still, is is much better than just capping the bottle back up with its own cap.

Works very well no imitations here I did have an imitation which was about $3 less than this and I had to return it because it wasn't pumping

I've found this to be an excellent product. I'll do my best to walk you thorough how I've obtained my excellent results: 1) After opening the 2 liter bottle of soda I cut off the remaining plastic ring from the top of the bottle. This is a MUST DO for this gadget to work properly. 2) Screw on the Fizz-keeper while it is closed tightly. Make sure the plastic washer is on the bottom of the Fizz-keeper. Mine is white. It is this washer that seals the Fizz-keeper to the bottle. Tighten the Fizz-keeper securely to the bottle but do not over tighten it. 3) Making sure the Fizz-keeper's bulb is latched completely to itself. Then simply pump the bulb. I hold the bottle with one hand, squeezing the bottle slightly as I pump the bulb with the other. You will feel the bottle tightening as you pump air into it. If it doesn't begin to tighten something is wrong. It isn't completely closed or screwed to the bottle well or missing the washer or detective. So when the bottle becomes slightly hard to squeeze it is tight enough. It is this preasure that holds in the carbonation. Don't over pump the bulb because this will build unnecessary pressure inside of the bottle causing the Fizz-keeper to be harder to open and resulting in a loud "pop". Maybe even blowing it off of the bottle causing injury or worse. You would have to be a pumping fool to achieve this much pressure but it could happen. Don't worry, with a little practice you will get the "feel" of all of this pretty quickly. 4) When I'm ready for some soda I press the release lever as I hold the bottle. Don't be supsuprised if there is a "pop" when opening. This is nomal and it assures that the bottle was pressurized and the drink should stll have carbonation. That's it. 4) The one thing I failed to mention: DON'T SHAKE IT! As with all carbonated beverages, if you shake them the preasure builds and POP goes the Weasel! I've had great luck using my little Fizz-keeper and I hope you will too. I felt $9 was a bit too expensive for this but after doing the math it's not bad. I don't go through 2 liters of soda quickly and I usually throw away a quarter of it because it's flat. This little dude has solved that. I realize this is made of plastic and polymer and it will dry out and crack and become useless. But if this thing works for 50 bottles it will have more than payed for itself. Then I'll buy another one. This review, like all of my reviews, is not paid for in anway. I only do this to be helpful.

My initial impression of the product was good. It seemed to be of reasonably sturdy construction and didn't feel particularly cheap. However, upon using the product, it became clear that it didn't work as intended. I gave it the benefit of the doubt, trying it on several different soda bottles before passing judgment. In each case, the product initially pressurized the bottles well but within a day, the pressure was gone and my soda went flat. I made sure the product was tightly screwed on and properly seated, but in each case, the outcome was the same. I thought perhaps I simply had a defective unit. Such things happen in manufacturing and it wouldn't be fair to rate a whole product line as bad over a single defect. However, upon careful inspection, I could find no defect. The rubber gasket that sealed the pump to the bottle was intact, properly seated and showed no obvious signs of being malformed. The hinge felt solid and the latch appeared to snap securely and seal. Nothing appeared defective. I can therefore only conclude that the design is itself is flawed. It's a shame. I liked the look and design of this product and I really wanted it to work. However, this product does not work as intended and I cannot recommend that anyone purchase it.

This worked for me after cutting off the lower bottle ring tab. Gives you just a little more space to tighten it properly. Also squeezed a little air out of bottle before firmly closing and pumping it up until very firm.

Did not like the explosiveness of how you have to open the pump to get to the soda. You have to close it good in order for it to work right. The white plunger pumps work better

On the bottles it does fit, it's an awesome device and works brilliantly. Few pumps and the contents are kept fizzy for when you next use it.

J'ai hésité entre ce modèle et l'autre de couleur blanche. J'ai finalement pris les 2. Je préfère ce modèle car le coté "boule" est finalement plus simple pour remettre sous pression, de plus pas obligé de dévisser, mais de déclipser. Seul hic, ce modèle est plus haut sur la bouteille, et du coup c'est moins évident que ca rentre dans votre portière de frigo.

A month in, the two Jokaris we ordered are still working perfectly. That can NOT be said for all the cheap ones we've tried -- they don't work AT ALL, right out of the package.

He tenido varios dispositivos para conservar el gas en refrescos, y este mecanismo es el mejor. La única duda q tengo es en cuanto a la durabilidad...

ottimo
