When my husband I needed to buy a new fridge freezer, we knew we wanted one with an “A” energy efficiency rating so that’s what we looked for first of all.  We found a number of models that met this criterion, but purchased one that had other features we were looking for.  We are very pleased with the Beko cda543fs and its many features that make using it a pleasure.   I have never owned a unit that has an automatic fridge defrost.  The refrigerator capacity is 5.5 cubic feet and the freezers capacity is 3.1 cubic feet, making it perfect for our family.
