I have been using this product for sometime and have no complaints whatsoever.  All the features and functions are top notch.  The ability to monitor the load via the SmartThings is super helpful.  When the drain is clogged,  it automatically alerts you on your phone and you can clear it off.  I run this at late night and it operates very quietly unlike the previous non-Samsung appliance and it didn’t let us sleep with it noise levels.  
The dishes are spotless clean with the manufacture recommended dishwasher detergent tabs. 

The self clean cycle is a great feature and helps reminds of general maintenance.  The app also helps you load the dishwasher correctly.
