Only one month since purchase, so I have nothing on longevity, however we love it.  Our main unit went down in the kitchen, so we purchased this unit for our utility room.  We really like the smaller footprint and design.  The smaller freezer doors are so much easier to open and close than the large bottom drawer on the main fridge as are the smaller french doors.  37 degrees keeps the items well cooled in the refrigerator and -1 does the job in the freezer drawers.  Factory setting was 0.  We were originally looking at something a little bigger and were glad we went with this one.  We measured, however the bigger one would not have fit so well.
