A:Answer The short answer: versatility. Here is a practical example: during the hot Summer months, having a bunch of ice cream, popsicles, and other cold treats on-hand is great, but during the cold Winter months someone might not want/need all those frozen treats. Instead of now having a bunch of freezer space they don't have any plans for, they can just convert it to more refrigerator space and store things they like to have during the winter (e.g. seasonal beverages). Another example: you could get a nice, big, frozen turkey months in advance and store it in this unit, and then gently defrost it by simply changing the unit's settings from freezer to refrigerator.
