Product review (2 stars): They don't fit!
The smaller pans fit the smaller burners fine, but the bigger pans are a bit too big for the burners, leaving a gap for food particles to get underneath. They slip around and interfere with the burner grate plugging into the stove "outlet". Sometimes when I turn the burner on, there is no heat, so I have to take it all apart and "seat" the burner again to make it work. These are a pain, and I really need to replace them....AGAIN.
