Purchased the glass top electric range.  It’s one of those induction tops.  Never used anything like it before.  Each burner knob has 2 settings on it (1 for a larger diameter, and 1 for a smaller diameter).   After a while, I decided just to use the setting, plus I don’t cook often.  Mostly soups made in the pressure cooker.  Will take the time to actually learn this product this upcoming weekend!
