What I love most about this cooktop is the smarthing feature. . I sometimes forget to turn of the stove but with this feature, there's no question if a burner is on or off. The blue LED Illuminated Knobs lets me know immediately if the burner is on. If I am out of the house, I can pull up the app and know which burner is on or not. I really like that!!  The sealed burners make for such an easy clean up. Thanks Samsung for making this stove easy to clean and know when it is on!!!
