(More customer reviews)Sorry Palmer (and the American Chemical Society) I have used the Fizz Keeper for more than 5 years and I KNOW it works! The only time any of mine have ever failed is when they have cracked around the top rim or when I didn't pump them enough times. I have one pump which is still working after 5 years. With care, I am certain your Fizz Keeper will last as long.
Here is the best way to use them.
1. Don't put them on a bottle until you have drank enough so that the pump isn't sitting in the drink. The sugars in the soda can cause the pump to stick.
2. As much as possible, don't shake or get the pump drenched in soda.
3. As soon as you're done pouring your drink put the pump back on the bottle, pump the pressure back up and stick it back in the fridge.
4. As the amount of soda in the bottle drops, you will have to pump the Fizz Keeper more times.
Here's how many times I pump it: Top 1/3 10 to 12 times. 50% gone ... 18 to 20 times. 1/3 or less left, 30 times. If you don't keep enough air pressure in the bottle, the carbonation will come out of the soda as the level drops and fill the vacuum left in the bottle. I pump the Fizz Keeper until I find it hard to squeeze the bottle in at its sides.
Don't shake the bottle as you pump. This agitates the carbonation and causes it to leave the liquid. Place the bottle on something solid, like a counter, and then start pumping.
5. As you pump, don't bang your Fizz Keeper. If it's making a clapping sound as you pump. You are pumping it too hard. Don't try and draw a full stroke on it, partial (3/4 strokes) will allow it to last as long as possible. Once it starts to crack around the top rim it's done for and you'll have buy a new one.
6. Remove and rinse it with water after the bottle is empty.
I hope the above helps all who are considering buying this little marvel.
I have purchased and used almost all of the various soda keepers on the market and this is the only one I can recommend. You are gonna love it and use it often!

I thought I would add the following. Though Kurt Greske is correct about air being more soluable in water than the carbonation. In a "closed system" like a plastic bottle that process will take some time to occur. Unlike your lungs (which are an open system) the carbonation has to go somewhere; hence the process doesn't occur immediately. It takes some time. As long as you finish the bottle within a couple of weeks I doubt you will even notice what loss does occur. After all, I doubt any of us would want to drink from a soda bottle that was opened two months ago. All I ask the Fizz Keeper to do is extend the life of the soda a reasonable length of time. For me, that's two weeks, maybe less.
