The old cooktop was on its last legs.  This GE Profile fit right in to the old cut-out in our kitchen island.  We like the fact that the grills are lifted a bit above the burners to even the flame pattern.  The grills are also solid and firm-fitting to the top.  What's more, the installation crew installed this cooktop more securely than the original.  The provided installation kit fit perfectly into our custom kitchen island.
