I love my new gas stovetop but there are 2 things I am unhappy with.  One is the knobs are plastic and I already melted one when a cookie sheet slid onto one.  The other is the open break in the grates...not sure why they need  an open space in some areas of the grates but when using a small pot such as a gray pot it gets off balance if it slips into the hole & spills all over the stove top.  Maybe there is a purpose for the break, but I can't seem to see why they are necessary
