We replaced an older GE gas cooktop with this new product. We chose GE because we’ve been pleased with the cooktop we have been using.  Also, a determining factor in our selection of GE was that the new cooktop fit the opening in the granite countertop without modifications.  Please ensure that all new GE cooktops that are the same size, ie 30”, as existing ones are designed to fit existing counter top 
openings.  It made the installation effortless and was a significant reason we stayed with GE.
