Title: An extremely successful scam
Review: I didn't think to question or research this wine preserver until after I received it. The principle SEEMS valid, but once I received it I questioned how effectively it actually evacuates air from the bottle. Then my research revealed questions about the stopper's ability to maintain what vacuum there is. So, I did a simple test. I pumped all the air out of a bottle that the unit was capable of and let it sit for a few hours. After only maybe 6 hours, the stopper was so easy to pull out (without releasing pressure first) there is no way there was much of a vacuum at all left in the bottle. At least it was cheap, but this unit is a complete scam. An incredibly successful and profitable one at that, it seems.
