Jokari Fizz Keeper Pump Cap for 2 Litre Bottles - 3.6cm x 8cm - Keeps The Fizz In - White - 4-Pack

I think I know why they do not work for some people, the length of the screw on the top of the bottle differs in so many ways on different manufacturers products. For instance, Pepsi, coke etc. all have longer threads for the cap to screw onto, where as Aldi and Lidl’s bottle screw threads are shorter, therefore the bottle stopper does not work properly, I had to remove the piece of plastic that was left behind by the lid and carefully screw the stopper into place, this is when the stopper makes a click because there isn’t enough thread to make a good seal. Having managed to make a good seal it was left overnight and when I came to it in the morning, as I slightly unscrewed the lid it popped off, so please do not scorn the stopper manufacturer when the fault is the bottle screw, please don’t think I have any allegiance to the people who produce the stopper (but if they want to send me loads of goodies for the review who am I to complain ) I just think people needed to know the answer as to why it may have not worked for them. Kind regards

No stars on this product from me - maybe the one I have just bought is faulty (we had one years ago and worked just as it was supposed to) but this latest one doesn't work at all - it won't expel all the air, so is useless and annoying that its taken three or four goes with it to finally realise its dud! Its making me give a rating tho I didn't want to give it any stars at all so bear that in mind that I have been made to add one when I didn;t want to.

A very good product. Saves money and reduces waste of sparkling water, lemonade, tonic water etc.I have ordered 2 x 2 of these. One of the first batch only lasted a few days before breaking, but the other one became such a good servant I bought more.I think they are a couple of pounds more expensive than they should be, but I have made that money back on drinks.

These keep carbonated drinks fizzy. Great for keeping tonic water coke and just about anything you can get in a plastic bottle. One thing you should bear in mind is not to over pressurize the bottle. It won't burst (unless you pump it oblivion) however it is worth noting that when you close the bottle after you have pour a drink gas is still being released, which adds to the pressure. I have found that if you can squeeze the bottle after pumping you will be ok. Over time I have found that when they have been in use for a few years... there is the possibility that they go off like a champagne cork as the thread gets worn down. Using the method regarding not over pumping... you will be fine. Storing these in the fridge does not seem to affect them. Been using these for over 10 years...

Well after about 30-odd years I decided to buy these again. Reason is that over 30 years ago these were the business for keeping the fizz in your soda pop drinks bottles, as we all know that once opened we fill the glass and then screw the top back on - not giving a second thought to the now pressure-less air gap inside the bottle to allow the gas in the liquid to escape into - thus your pop goes flat pretty quickly!Needless to say these are not of the same build quality and construction and quality of those back in the 90s... and it shows as it seems like you are pumping for ages just to get the desired pressure to ensure the pop keeps its fizz - and as such you can clearly feel that the air pressure only really forces air into the bottle on the last 1/5 of the full pump stroke. This is not what it should be as it take 5 times longer to pump the air you need.So with this, although they do work (BUT only on some types of bottles - as after some build up of pressure the screw thread can't maintain grip and blows off so you can never really seal it shut tight) they are a great device... but there must be better alternatives out there that do a better job than these.So onwards with looking...

Works sporadically

One was just too big and wouldn't fit on any bottle I tried. So I threw it away.The other just about fitted my lemonade bottle, but I have to be very careful not to overtighten, as it will just 'click' and go round again and again.When I'm able to make a good seal, which is not easy without over or under tightening, the pump action works well. But more often than not, the seal is not 100% and it slowly leaks down to about 50% pressure.

This is a simple to use and effective product, certainly keeps the fizz in the drink till the last drop

I have been looking for these for a long time, until I found them on Amazon, with a lot of searching. I used to have 2 of them many years ago, but they somehow got lost. They do keep the fizz in your pop/soda if you use these correctly. To keep the fizz in pop, you have to pump air "into" the bottle. You have to pump many times, especially if it is a 2-litre bottle. Pump (many times) until the bottle is firm and you are good to go. This acts as a pump and a lid for the bottle.I am so happy to have found these.

It is a good product , just need to put in a little work of pumping but then all's good

Als ich nach so einem "Teil" suchte, wusste ich nicht, dass es so etwas gibt. Daher einfach mal im Web herumgegrast.Und tatsächlich, es funktioniert total zuverlässig.Kurz gesagt: Kohelsäure bleibt da, wo sie hingehört - in der Flasche! :-)

This would probably fit a US soda bottle, but the ones in europe have a shorter thread section and the bottle lid remains attached to the bottle. Even if you remove the lid and use strong scissors to take the plastic ring that holds the lid, it still doesn't make a seal. So we had to return it.
