The size of ice cubes is determined by the thickness set by you. Thicker ice means bigger ice cubes, thinner ice means smaller ice cubes. The actual size is based on the ice thickness number set by the user.
Instruct users on how to set the ice thickness: long press the plus key for 3 seconds until the number on the right grid flashes, then short press the minus key to reduce the value. Setting it to -4 or -6 is more appropriate https://youtu.be/mqvHUn7tlc0
