Jokari Fizz Ninja Pump and Pour Soda Saver For 2-Liter Bottles, 1-Pack

Works good. Some of the reviews stated that they don’t work. I don’t know how that is unless they were defective or they never pumped. The less soda in the bottle the more you have to pump to maintain carbonation. If you leave only a glass worth in a 2-Lt for a couple of days then it doesent do a good job. I can leave a bottle for a week half empty and still have plenty of fizz.

I like these "fun" yet practical fizz keepers. They do a sufficient job on a 2 liter bottle, that is until the carbonated beverage is down to the last 3 to 4 inches from the bottom. Prior to having these Ninjas, the "fizz" would be gone just halfway through a beverage of a plastic bottle, and/or within simply a day and a half or two. The Ninja's are worth it, but even though the Ninja's are easy to thread on and snap closed, the continual squeezing of the bulb (Ninja Head) with the fingers can get tiresome. You have to do that in order to reinflate of sorts to maintain "pressure" in the bottle. Once you feel resistance while squeezing, you will know that you are done till the next time you pop the Ninja top open again. Cool how with a slight push of tab on the Ninja, the top flies open with a loud pop and swoosh! Always "fun" in trivial little way. *Note, the lower the level of the beverage in the bottle, the more squeezing that will be needed to restore sustained pressure, so that might be difficult for someone with arthritis in their fingers/hands.

I just used one for the first time, but it is not my first one. I bought one and it is in my home, i needed one for my camper and they work so well, i’m A Pepsi feen and I never drink all in those plastic bottles, and these work well. For me, I would and have to throw a lot away becasue the Pepsi today, is not the Pepsi I grew up with and after a short while, it goes flat and I hate flat pop! The bonus with these, they are like little ninja’s so the grand kids will like them also.

I love this product I have lost one already unfortunately. I had a one l bottle of soda in the refrigerator at work and forgot to bring it home and had 3 days off. There were 2" of soda left in the bottle yet it was still fresh as if I had just opened a new bottle even 3 days later. I hate flat soda and was spending a ridiculous amount for a little 16 oz Soda at work for a 1.50 each and some days I was having 3 of them. Saving lots of $$ with these.

Works great. Works moderately when 2 liter gets near empty and has been sitting for several days, but I guess that is to be expected given the laws of physics.

These little guys work very well. If you drink soda out of plastic bottles and can't finish it in one sitting, these will help maintain your carbonation. I was skeptical, but I am a fan of these little ninjas!

These do what they say they will. Since 2 liters are so much cheaper than individual drinks, they can pay for themselves pretty quickly.

I rarely write reviews, but this item is the best. I have used Jokari Fizz-keepers for years. But the Fizz Ninja is easier to use and keeps soda fizzed for days. One disclaimer, I have not used it on large liter bottles, only the smaller size bottles.

Excellent tops work great excellent and when cap released gas out but cap secured great product worth every penny.

There is supposed to be 2 in a pack. only got 1 so far. surely they would not send them separate.

just what we needed ideal.

Love these....getting more ...good gift as well.

They work, I am pleased with the serviceGeoff
