As there is only my husband and I, we bought the 18 inch  to gain extra cabinet space.  We paid more than we would have for a full sized model because it is special order.  It has no extra features.  It is very hard to load because tines too close together. My dishes are heavier stoneware.  The silverware slots do not accommodate my silverware and had to take them out (the partitions)   There is no way to tell if the load is done,, no "clean" signal.   I actually dislike it very much and would not repurchase.  My last dishwasher was also A small GE and was fine
