i like the non protruding door handles.  they give a clean line appearance.  comes with a thin protective film around the front which i found difficult to remove.  in my experience this film is firmly attached under the door gasket and tears away leaving behind fragments.  
   the manual gives clear instructions.  for example, to change the water filter you will first turn off your water supply valve.  after a simple twist and pull of the old filter you insert the new filter and twist.  the manual then  suggests a 7 minute water line purge.
  i like the special setting to have 3 days of accelerated cooling.  my experience is that all food has remained chilled or frozen.
