The Houdini Wine Preserver is superior in removing air from your red wine bottle to better preserve the flavor of the wine. This is accomplished 3 ways: (1) the pump handle is ergonomically designed to afford easier pumping action and to avoid pinching that can occur with other pumps; (2) two push–button stoppers are included, employing a patented valve that holds a vacuum for days and releases it at the touch of a button; (3) bottles sealed with push–button stoppers can be stored horizontally--those sealed without the push–button stopper must be stored upright to prevent leaking.
