The "floating widget" ball actually makes for the unique foam, to an Irish Stout makes them so special. Not to compare with the "Guinness Extra Stout" from the supermarket, taste, this variant of the can almost like freshly tapped in the pub and is - the equivalent of '1,66 / tin - also really inexpensive!
The only drawback, for it is not worth deducted a star is, that you can not quite fully get the nice pint glasses, as there are in the can just 0.44 L.
Otherwise this beer is highly recommended and should be in the cabinet at any Ireland-friend!
PS: The empty cans they will go again thanks to the new deposit system on each machine.
