After wanting one for over twenty years, I finally acquired a glass cooktop in 2002 when we remodelled our kitchen. My favorite feature is ease of cleaning. A razor blade removes the crustiest stuff, while a paper towel and a paste cleaner remove the rest of the spillage. It takes less than 5 minutes, while the old drip pan system took much more time and effort. It has four burners, two of which are connected by a "bridge". This is great for my water bath canner and other large pans. The third burner heats either a 6 or 91/2 inch area, depending on the setting that you chose . The fourth burner is 51/2 inches. this allows me to choose the proper burner for each pan I have, so I don't waste electricity heating more burner than* *I need. In 2005, I dropped a heavy glass on the cook top, which caused a crack that "spider webbed" a major portion of it. After rearranging the cupboards to put only light plastic items in the cupboard over the cooktop, we replaced it. Note:The above model number refers to this second top. I have had no problems with this cooktop. I have recommended it to several people and I will NEVER use any other type of cooktop.
