Have been delighted with this product since I bought it, but recently I had a third of a bottle of prosecco which I left in the fridge by accident before going away for a week. I fully expected that it would be flat and need to be thrown away when I got home so was absolutely amazed to find that it was every bit as fizzy after over a week as when I first opened it. It is hard to imagine anything could keep bubbly fizzy for over a week but it really does work!!
