What's an oz Stanley Quencher and how did you break 64 of them?
On a more serious note (and after converting that to units I understand... it's about 1.8L) I'm sure all the quality products I know of aren't even half that big. That's nearly the daily amount of water recommended for an average grown-up.
EDIT: Googled a bit to check and yeah... 0.8 to 1.2 liters are the usaal XXL sizes. Everything above that seem to just be cheap Stanley Cup clones.
