The cooktop is everything it's supposed to be.  Very robust compared to our old cooktop.  The only problem with it is that the grates are very heavy.  If you get some spattering, to clean it, you must pick up the heavy grates and put them down somewhere to get them out of the way.  It's an inevitable problem if you are going to have big, heavy-duty grates enabling an unbroken surface across the stove top, but it's an issue if you're not up to lifting heavy grates.
