I had a new cooktop chosen to replace my old GE cooktop, but they were going to have to cut the Corian countertops for it to fit. Rather than go to that trouble, my installer told me to see if another cooktop would fit perfectly. How happy I was to find a GE cooktop that that fit perfectly into the space. I am so pleased with the quality and performance of my new GE. It was also more economical than all the other ones that I considered.
