I'll start with what I love the most about this drier, and that is the auto sensor.  It knows when my clothes are dry.  I set it too auto and leave.  I come back and my clothes are dried to the level I had set them to.  I stick my head in the drier and look for the sensors, I don't see any lol  .  How it knows, I have  no idea but it fascinates me that it can distinguish between very / more / normal and damp.   And it so quick, 45 minutes (my old drier sometimes took upto two hours) for an average size load.  And unlike my old drier that had that old buzzer sound that went Bzzzzzzz, this Samsung electric drier plays a cute musical tune to let you know that your clothes are ready.  Now if drier could only fold the clothes.....  Maybe the next model I purchase from Samsung in a decade or so will have that feature.  The photo below are the family refusing to fold and from delivery day.
