Query: Could it really work? YES, its a great Wine accessory!

When I first got the Wine Saver, I had looming doubts. However, after much skeptizm, it definitely exceeded all my expectations. You can literally save a bottle of wine to as newly uncorked for up to 3 weeks. Great for red as well as chilled white. I recommend this to anyone who enjoys wine and seems to end up with some left in the bottle at the end of the evening!
