Jokari Keeper Pump and Pour Soda Bottle Cap Preserves Carbonation with Flip | Flip Top Spout, 1 to 2 Liter Plastic Bottles, Preserve Soda Carbonation, Fits Most Plastic Bottles, Pump and Pour All-in-One

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.

This gadget is a game changer!! It really works to keep the fizz in your 2-liter pop. Since usually the cheapest way to buy pop is in 2 liter bottles, it will save you money. Liked the first one so much I bought another.

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.

I have used this for months. It works very well though it won't last forever. It keeps it fresh and I have several glasses of soda per bottle

Works well!

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 device Gives me 3 full days fizzy store brand soda. I drink quite a bit of Kroger brand and Publix brand caffeine free soda prior to having this device. My drinks would go flat middle till later part of day two after having opened the soda this device has the drink still fizzy on day, two, and all through day three. By then I’ve usually consumed the whole bottle on my own. Prior to purchasing this pump, my 2 L bottle would be flat with 1 Liter of soda still in there. By owning this pump, I have reduced my soda waste. I don’t know about the longevity of this, as I’ve only owned two months, but in the two months I’ve owned it. It has paid for itself. Some of the negative reviews people are complaining. It doesn’t keep fizz a week, but who takes one week to consume a 2 L bottle of soda? Others have complained. The orifice is narrowed and the soda doesn’t pest freely, well that’s not a big deal. It’s only slightly narrowed, if anything soda pours easier now especially if you were an older person he might have trembling hands. Another concern people have had is how long will the hinge last? I don’t use the hinge that often many times I just unscrew the device. Please watch my video. The soda I am pouring out is on day number three. Also I’ve never needed to cut off the ring on the Kroger, Publix or Walmart sodas to achieve a tight seal with this pump.

They're okay. It takes way too many pumps to keep the soda carbonated, which seems to have a law of diminishing returns anyway... Fits well, seals well, doesn't leak. Takes forever to pump it up, and...honestly...I would rather finish the bottle.

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...

Exhorbitantly overpriced, I found same from the manufacturer itself at two thrds the cost including shipping but too expensive to return since shippibg back is at my own cost. Amazon has been useless as it only showed the one seller and I had bought previously in pack of 2 so I thought I was paying for 2. Manufacturer website also said usually sold in 2's. Only found out by chance when I searched again. I paid about $33 when the cost from manufacturer online is less than $20. Amazon, NEVER AGAIN will I buy from you.
