Our builder installed what we thought were quality appliances in our new home. We have Wolf and Sub-Zero. The Wolf line is very good, but the Sub-Zero refrigerator is not what we thought. It looks great with a stainless steel exterior, modern handles and a clear/glass interior. Although it looks like a large unit, the freezer is very small due to the ice maker and shallow shelves. The refrigerator section has plenty of slots to adjust the shelves, but the shelves cannot adjust much because the upper shelves have different widths. The crispers are not temperature controlled and cause the produce to wilt. Other brands we have owned, like the built-in Kitchen Aid, have much more usable space. We would not buy this model again.
