Dual flush systems on the other hand are horribly non standardized an inconsistent: https://duckduckgo.com/?q=dual+flush+buttons&kp=1&iar=images&iax=images&ia=images https://duckduckgo.com/?q=dual+flush+buttons&kp=1&iar=images... On some you press the big section for the big flush, on others you have to press the big and small, sometimes the half flush is the bigger "default" button and others can be confusing with nested levels of depressions to mark them. Throw in no directional standard like the half flush being on the left and the whole things one big (pardon the pun) crap shoot.
