This cooktop replaces an ancient GE cooktop we inherited when buying our new house. The old cooktop had a blue surface which didn't show stains or spots easily. The new glossy black cooktop shows every water spot or stain. Other than appearance, the cooktop works well two months after installation. We did have a problem with installation, as the new cooktop was about 3/4 inch thicker than the old GE cooktop, necessitating some alterations in the drawers beneath the cooktop. Fortunately, there was just barely enough extra space to move the drawers (without interfering with cabinets below them) and fit in the new cooktop.
