Summary: Newer stoppers for fresher wine
Comment: These new model stoppers seem to allow more air to be pumped out of a bottle.
Looking at the reviews of this an other Vacuvin products, you see reports that are deeply contradictory. It's interesting that there is such a divergence of experience with such a simple product. The ideas behind Vacuvin are pretty simple.
First, air is the enemy of an open bottle of wine. Bacteria in the air want to turn alcohol into vinegar. The air itself oxidizes and dulls the taste of all but the most robust wines.
Second, you can remove some of the air with a simple pump and thereby slow down the rate at which wine deteriorates.
Why then, do we have both no-star and five-star reactions to this product?
Maybe the biggest source of disagreement is expectations. Vacuvin slows the deterioration of wine in the bottle, but it doesn't stop it.
Another possible reason for all the disagreement might be a question of temperature. The biochemical reactions that kill your wine are temperature sensitive. They proceed faster when the wine is warm and slow down when it's cool. Putting a pumped-out bottle in the refrigerator or wine cooler will slow down the spoilage processes and make Vacuvin more effective.
A third issue is the way the wine is handled before the Vacuvin plug goes in. If wine has a lot of air dissolved in it by being poured from decanter to bottle, there's no system that will keep it fresh.

Summary: Vacuum Wine Saver Stoppers
Comment: These savers are very efective as vacuum stopers to help preserve opened botles of wine.

Summary: Better get a couple of these
Comment: When you get tired of searching the kitchen drawer for one of these gray corks for your wine leftovers, realize that the last one probably DID roll under the fridge or become a chew-toy for Fideaux. So have a packet of these on hand.

Summary: There are cheaper and better options to save your wine
Comment: The main goal in keeping wine "leftovers" is to prevent the wine from aging between the time you open the bottle and when you finish the remaining wine. Air destroys wine, so you need to minimize the air contacat. You also have to keep the wine in the fridge during this time, because 55F is a 'normal aging temperature' and since the air is already aging the wine, you want to minimize *any* other degrading that might go on. Any temperature over 55F will simply make things worse.The vacu-vin attempts to help by sucking the air out of a half-empty bottle of wine. Note that, instead of the few pumps their literature suggests, you need about 15 pumps to get most of the air out. For many wine types the fact that you are in essence lowering the pressure in the bottle pulls the 'liveliness' out of the wine, which ruins it.
I have done a series of tests for my website comparing both a red and white after 3 days, being stored under a variety of circumstances. The vacu-vin "works" in the sense that it does remove most of the air. However, it was also found to greatly harm some wines - even when you compare its use against a simple cork.
The *ideal* method of saving wine is cheap. Simply put the wine into a smaller glass bottle, cork it, and put it in the fridge. That has the best chance to keep the most common wines for another few days in the best condition. No air at all, no vacuum either. Of course, *no* method will really keep a wine in the same state it started in. You can always cook with the wine on the second day, and move along to your next bottle!
Life is too short to drink bad or old wine :)
