Product review (1 stars): Don't Sit Well on Stove
I have a whirlpool gas stove and find these do not sit flat on burners as they are not deep enough.  They appear to be crooked and bent when laying on burners so I don't use them regulary to sit on stove but I do use them when cooking on only one or two burners to help keep grease and other cooking material from landing on and around burners I am not using.  However, disposable pie tins would do the same thing and would be easier to store.
