The Draft Top® was specifically designed for most standard 12-16oz aluminum beverage cans and some 19oz cans with standard tops. It does not work on crowlers, 24oz tallboys, 8oz Redbull, the Sam Can or soup cans. There are certain regions of the world that produce different can lids and some are not compatible with this tool. The can diameters that fit are 52mm to 57mm. That includes Seltzer and Whiteclaw cans.
