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.

Works well on my Sainsbury's Cream Soda 2L but, unfortunately, does not fit Dr Pepper Zero 2L, which is the main one I wanted it for as that goes flat very quickly (hence only 4 stars). 😭 Perhaps, as several fizzy drinks manufacturers seem to have reduced the size of their lids slightly, they should make it in different sizes? I would definitely buy another if they did.

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.

My Pepsi was flatter the next day with this useless object on it than without it. Total waste of money.

Fitted the bottle okay, pumped up okay, ginger ale went flat overnight so something not quite right with this gadget, or at least with the one I received. Not as if it was from the £1 shop. Returned for a refund.

I was dubious at first, as the plastic didn’t feel very robust BUT it works really well. Brilliant for our tonic bottles when we don’t use the whole lot. Good delivery, on time. A good buy.

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

I'm not going to say this product is rubbish because basically it does the job and well. I purchased two of these back in July that's less than six calendar months to the day of purchase. Today, one of them has stopped working. The non return valve will pump air into the bottle but on releasing pressure on the rubber bulb, the device sucks the air back out again, which IS rubbish. There does not appear to be any fault in the rubber for example a puncture. I would have given one star, but for the fact this product is used several times daily so perhaps it's not meant to be used so frequently. Even so it's very dissapointing to have to consign such a useful thing to the garbage with less than six months usage.

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

しっかりと炭酸を閉じ込めてくれます。2〜3日なら大丈夫かと思います。 （それより前に飲みきってしまったので⋯）
