I waited three hours to check on the ice cube trays. One of them is partially frozen, the other three are not at all frozen. This is in a freezer set to -5°F and that has a history of freezing things so hard it takes days to thaw in the fridge (and several hours on a counter). It’ll freeze a pound of hamburger rock hard in three hours. What the actual hell? At this rate, four trays will never be enough, and I don’t think filling the entire freezer with trays would even keep up with my household’s ice demands. I better get to researching those countertop ice makers.
