This stovetop replaced a 12 year old Kenmore Elite that had an igniter that was not working properly. It’s so much better!  The large burner quickly heats water to boil, the small burner is just enough for a simmer. The grates are higher than my last one but even with the above stove microwave/vent, even my large stock pot fits. The grates are very heavy but they don’t move around if you have a heavy pot that needs to be slid to the front. I love it!
