Good idea but doesn't work as intended.
Scratched our stainless steel dishwasher. Also resulted in much consternation when it didn't work to remind family that the dishes were clean before they put more dirty dishes in along with them, resulting in the entirety needing to be cleaned again. The thing that would actually work with our dishwasher is if the first person to open the dishwasher with the clean dishes inside (ours makes a chime at this point) actually put them away instead of expecting someone else to do so later in the day.
