We didn't even know that it made "Ice Balls" until we heard a crash in the bottom freezer. Unfortunately, that was the first problem with the it.  Then, the ice maker in the door stopped working all as it approached 1 year. Then, the big one, the unit could no longer keep the freezer or refrigerator at temperature. Food in the freezer thawed and we couldn't trust the food in the refrigerator so most of the items had to be thrown away.
