Have been using this cooktop for about 2 weeks. The burners and griddle are all great and what were hoped for. The quality of the stainless is far inferior to what was replaced after 7 hard years of use. Can't imagine the finish of this cooktop maintaining any level of beauty very long. Extremely susceptible to scratching - watch out when removing or replacing the grills after cleaning.
Perhaps the Monogram would have been a better choice. I imagine in a couple years we may find out...
