We have integrated subzero columns (24” freezer and 30” fridge) with internal dispenser…NEVER use the dispenser…agree with @hallettco about standing at an open fridge to run water dispenser ). No problem so far though (3 years). I prefer columns because I don’t like having to rummage through a freezer drawer. We also have a 48” Wolf dual fuel range (w/griddle). Very happy with that as well. We have had NO blue chipping problem and I DO use the self clean feature….no issues there. One of the instructions from the manufacturer for using the oven was never to wipe down the blue interior surface with water while the surface is still hot/warm. I always wait for it to cool completely before wiping interior after cleaning. We also have a GE Monogram french door oven which I really, REALLY like and use more often than the Wolf ovens. Its simply more convenient because of the french doors, and being a wall oven, is much easier to access.
