This item seems well-made, but there are two glaring design flaw.  When you open the tap, some soda (or beer) comes out, but not much.  A vacuum is created in the bottle, which stop the flow of the contents inside.  With no way for Air to get back into the bottle, it locks up.  Also, you will only get half of the contents out of the bottle, because the level will equalize once the remaining contents of the bottle are the same level as the spigot.
