The cord for the flush knob broke at the lifter inside the plastic casing. wasn't even very corroded just snapped off.
i see a lot of reviews for the same thing. only last about a year. mine was the first generation, the dual valve didn't work as good as i hoped. half tank flush had to be at max, an i had to hold it for a few seconds for it to clear the tank.
still less water than the full tank flush. i'd buy it again but i only need handle and flush part, still have fill valve working fine.
replaced for time being with old flapper style. kinda of suck to buy it each year.
