Product review (4 stars): Good, but a redesign of the button should have been made.
I replaced my original circuit board because one of the buttons used often ("button to switch between cubes, crushed ice, and water) became worn and constantly actuated. The replacement item works as designed - it is the same revision as the original. The problem is that it does not fix the original issue of a poorly designed button. Over time the same issue will happen again.
