It sucks, but it also blows a little
on November 6, 2006
I bought this item as a resplacement for another that had lasted several years before succumbing to the demise to which all devices with cheesy plastic parts eventully succumb. Fortunately, the Swissair I replaced was for use both with wine (suck out the air) and bubbly (pump air into the chamber), and the busted bit was stuck in the wine position, which was fine for 99% of its service.
Like a dummy, I got the Metrokane and chucked the Swissair in one irreversable transaction.
The Metrokane is servicable. It does what it purports to do: It sucks the air out of the bottle. If that were the whole story, I would undoubtedly give this product a 5. Alas, the value of the vacuum is only as good as the staying power of the vaccum, and that requires that the stopper provide a robust seal. To put it simply: The seal seems to be the weak link in this system.
If I pump the bottle, and immediately let out the seal, I get a satisfying hiss, indicating a positive seal. If I pump the bottle and wait a day, the hiss is a little less satisfying, indicating a slow leak. One might expect the day-later hiss to be diminished for other reasons (whatever it is that goes on inside the open bottle), but in comparison to the swissair, the next-day hiss is too differnt from the immediate release.
I have found if I wet the stopper, that helps, and the resulting seal can last a few days with very slow loss.
So, I gave the product a 4 -- it works, but not as well as what it replaced, and I think that issue is with the stopper, not the pump.
