It is so quiet - incredibly quiet - that you have to get near to tell if it is on.  I thought a dishwasher was just a dishwasher until this thing showed up.  Sure, it cleans dishes.  But, this looks great, fits the decor of the kitchen and runs in total stealth mode.  When you have an open concept, well, the noise of a "normal" dishwasher can drown out conversations in the living room or even the TV.  Not this guy. Turn it on and it will whisper sweet nothings to those dishes to get them clean.  It is so quiet, that we have opened it while it was running, thinking it was off.  The fact that I can monitor it and the Samsung fridge on the SmartThings app is also pretty cool.  Highly recommended.
