This item works okay, but be careful. ALWAYS OPEN AWAY FROM YOUR FACE! It's probably best only to use this if you have half a bottle of soda left. If you use it after one glass of soda (3/4 of bottle or more) then you can very easily over pressurize the bottle and when you go to remove the pump/cap later...BOOM! The pump/cap will shoot off like a rocket and hit the ceiling and then your pop will spill out all over the place. Also with like less than a half of bottle you have to pump the thing like 50 plus times or more, not real convenient at that point, but it does seem to work.

I was thinking of gluing a golf ball to the top to use as handle, using Shoe Goo. All these soda fizz keepers, whether this brand or generic (generic seals go bad fast), the plunger disc is same diameter as the cap. It makes my skin gets pinched between them when you push plunger down. Diameter of plunger grip needs to be at least 1/4" larger, to keep skin on my hand away from contact on cap and getting smashed. It makes me not be able to pump efficiently - OUCH !

Pros: It makes you think its freshly opened each time you crack the cap because of the fizzle sound. Cons: 1) Each time you drink the more pump strokes it needs to pressurize the bottle. The most I've pumped is around 55 strokes. 2) I've pinched fingers between the plunger and it's base every time I used it. 3) Hard to unscrew under pressure. 4) Doesn't prolong the flavor of the soda at all. 5) One time it was lost and found it attached on the bottle in the recycling bin.

Best product on the market that actually keeps your soda from going flat. It has also saved me money because now my soda stays fresh and lasts literally until the last drop is gone. Without this product, my 2 liter of soda would last about 2 days before going flat. Best product ever!

I'd say this helps prolong the life of your soda by about 50%. Considering that there's very little you can do other than re carbonate the soda, I'd say it works well enough. It takes quite a few pumps; about 10 pumps for every 1/10th of the bottle used. So 10 pumps for 90% left, 90 pumps for 10% left. For what it is, I would expect to see this in the dollar store sometime in the future. $7 is a little over what value I think this has.
