I was so excited to update my kitchen to the Samsung Brand.  I am thrilled with this cooktop.   It's sleek, elegant and efficient.    There are 5 radiant cooking zones, 2 that have a pan size selection for versatility.  The 2 elements on the left of the cooktop can be synced to work together for larger pots or a griddle, which I love because I get even cooking throughout.  It's fantastic when I am cooking a large pot of potatoes or griddling pancakes. The power level of the radiant elements can be controlled by the detachable magnetic control knob or by digital touch with precision.  It has a rapid boil option, hot surface indicators and a lock option for added safety.  The wifi allows me monitor my cooktop from anywhere.  Samsung put a lot of thought and care into designing this cooktop for efficiency and convenience .
