Love the cooktop, but the knobs do get hot when using larger pans on the front burners. They could have placed the larger burners towards the back, and the smaller one in the front. Also, after I installed the cooktop, we noticed that there was some rust already on the grate, so I scrubbed the rust off, I think I got it off, but I’m hoping it doesn’t come back. This shouldn’t happen on a new appliance.
