Prime user Lloyd : Iffy

These are tricky. You need to make sure you get them on the bottle properly and pump enough air out to keep the soda from going flat. It also seems hit or miss if the tops in the bag will work. Not a real fan of this brand. If they work they work well. Again, you have to make sure you get them on right and pump enough air out.

Charlie Litton : meh

Got a package a 5, and the first one didn't hold pressure, so the beverage went flat. The second seemed to work okay though, so this might be one of those hit-or-miss products. If you buy it, expect a few of them to not work very well.

Armando Becerril : Sucks

Did not hold pressure

MyOhMy : Keeps my pop just as fizzy for longer than it would last with the lid.

They work. I have the wine stoppers like this that do work so I took a chance. I usually can't finish a bottle of soda at one time and by the time I do, it's losing it's umph. I put one of these babies on my soda and came back for a second glass later and it was just as fizzy as the first glass. I have been using this on 16 oz. Bottles but I'm going to branch out to larger bottles and see if it works as well. (Crossing my fingers).

chloe shear : Does NOT work

Tried full package of 5, none held carbonation.

Frank Bendrick : Does Its Job

Seals well. Pumps up and holds pressure well. Excellent product.

KC : Easy to Use, Work Pretty Well

This set of 5 FRESHeTECH Soda Sealers - Air Tight Soda Sealer come in a nice pack of 5, and are very simple to use on any standard plastic carbonated water or soda bottle. You just replace the regular bottle cap once opened with one of these sealer tops, and screw it on the same way. You then push the top of this sealer cap down repeatedly until you can't easily press anymore. I believe this is adding air into the bottle until the air pressure in the bottle is strong enough to prevent further carbon dioxide from leaking out of the liquid into the empty space in the container. This works well, and I can hear the fizz strongly when i open the top the first few times. It loses effectiveness over time, but that would happen with any cap you keep taking on and off. Does this work better than just a regular cap? -Yes, a bit better. Is it worth looking around for this and switching out caps? -Depends on how long it takes your family to get through a carbonated beverage bottle.

Barbara K. : Doesn't work

Used a cap and followed instructions on how to use, but the next day the bottle was completely deflated as if I didn't even pump all the air into the bottle to make it hard. Waste of money for me.

Rosemary rosiebear Pfeiffer : Really works

I love that they fit on any size bottle! Very easy to use. Just replace this instead of the bottle cap....pump it a few times until the bottle gets hard. You will hear that hiss when you open it.

David Page : Don't buy, spend a little more

One of the caps broke after one use. Does not hold enough pressure in the bottle to keep the carbon in a compressed state, in other words, gas will leak through the cap.

Robin : Works really well

Keeps pop from going flat when only about a quarter left.

Amazon Customer : It really works.

I keep big bottles of Sprite in my refrigerator and they stay fresh.

MyOhMy : Keeps my pop just as fizzy for longer than it would last with the lid.

Charlie Litton : meh

George L McCullough : Product does not work great

I am disappointed with this product as it does not keep the soda or sparkling water fizz from going flat

Barbara K. : Doesn't work

Used a cap and followed instructions on how to use, but the next day the bottle was completely deflated as if I didn't even pump all the air into the bottle to make it hard. Waste of money for me.

Carrie Davenport : Does not work

Doesn't work!

Bill Cashell : It Really Works

I am usually a bit skeptical about products like this because they seem a bit like a gimmick. Also, I have never found anything that would keep carbonated beverages from losing their fizz because I believed that once you open it, it will get air in and there is nothing you can do about it. In this case, it really works.

I opened a 2 liter bottle of soda and took out an 8 oz glass. Then, I put on the correct lid and pumped it until I could feel pressure. I put it back in the fridge for 3 days and took it out. Surprise! It was still fizzy.

I removed another glass of soda and put the cap back on for 2 more days. After opening it, I noticed it had lost a bit of it's fizz, but it was not flat. There was still enough to make it tasty.

I am anxious to try it with a bottle of wine. That may be a little harder because my wife and I don't usually leave enough to save. Perhaps I need a bigger bottle.

Armando Becerril : Sucks

Did not hold pressure

Katharine R. Mueller : Awful. I'd give it ZERO stars if I could.

These soda sealers do not work AT ALL! I can screw it on, pump it up, make the bottle feel nice and hard (that's what she said) and then the next time I go to the fridge, the bottle is full of air and soda is flat. I thought that maybe the first one I used was just a dud but this has happened with all of them. So sad. I really hate flat soda :(
