We bought this unit for our vacation cabin. We're hunters and often have a lot of extra game meat or fish to store, and the freezer in our refrigerator just doesn't have the necessary space, and even those it's normally winter when we get this game, we don't trust storing it outside. This unit is ideal for that bit of extra storage space you need for extra meat or whatever you're storing for later use. This unit has been a lifesaver AND it doesn't take up a lot of room. Yet it has a lot of storage space inside. 5.5 cubic feet might not sound like a lot, but it is! We picked up ours on sale, so it make it an even better investment. Temperature Control You basically just dial how cold you want it. We've found that we don't have to go much over midway (#5) and it gets the food to at least zero degrees. More than adequate for us. Capacity 5.5 cubic feet is a lot more space than you would think. Just make sure you make your food, while it's still soft, into flat shapes or square ones so you can fit as much in as possible.
