Jokari Keeper Pump & Pour, One Size, Black

It works. Gave it the ultimate test. A 3l lemonade used by one person. Finished it after almost four days and still noticeably fizzy. Normally yhe last .5l is totally flat and is chucked. Gives a lively pop when released. Well worth a tenner.

Easy to use, does what it says.Hope it lasts, hinge is sometimes the weak point in this type of fizz keeper

Easy to use. Have in the past used plunger type ones. Over a short time I found they lost the air/pressure. The design of this one looked after should last a considerable lot longer, so therfore a good value for the money. Used to keep the spark/fizz in large bottles of spring water (can't get the smal ones) I would highly recommend it to everyone be it for any fizzy drinks. Will be buying another couple.

Worked fine the first time. The second time there was a hiss as I pressurised the bottle and the unit had split making it useless

My husband bought this thing as he likes his fizzy drinks fizzy. It's the business! Works perfectly, great invention!👍👍

A neat product that works well but unfortunately around 12 months ago (in the UK at least) coca-cola introduced bottles that used less plastic. The openings are a few mm smaller in diameter & the bottle plastic is slightly thinner, as a result this bottle fizzer just doesn't fit the new tops making it pretty redundant for my use case. Just a warning for anyone else who wants to use it to keep their Coca-Cola bottles fizzy.

At first I thought this device was excellent. It was easy to use and seemed to work very well in keeping fizz in the bottles of cola I used it on. However, after only using it on three bottles, the bulb bit sheared off on one side, rendering the pump action inoperable. So I returned it. To be fair, it may have just been a one-off dud, so I'll see how the replacement performs, and if it survives I'll revise my review accordingly.

I've tried lots of different brands to keep my lemonade fizzy and this is by far the best I've come across. When my current one fails (as they all do in the end) I'll certainly be reordering another.

gotta say was not convinced till I tried this here gadget, it does work! keeps carbonation better than any other gadget have tried, takes little to get used to the more empty your soda jug the more pumps it takes till pump ball shows resistance.

Es muy bueno y si mantiene por más tiempo con gas las bebidas, sólo midan muy bien el espacio de su refrigerador porque a mí me quedo más grande y la tengo que inclinar un poco.

Great product, does exactly what is says it does.

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...

Ich hatte bereits noch ein Paar solche Teile ausprobiert.Diese hier macht es am besten bisher und nach ca. 30 Flaschen funktioniert immer noch.Er hält in der Tat die Sodas länger mit "bloop", also macht er was er soll.Aber bei eine halbe Flasche über nacht erwarte kein Wunder - mein Cola hat zwar mehr bloop wie es ohne der Keeper der Fall gewesen wäre, aber der Cola war nicht wie frisch geöffnet.
