The fit to the stove is not great, you have to deform the aluminum foil so it sticks.
But the worst problem is that some burners are a different size, whereas these foils
all have the same shape. Worst though is the fact they don't cover up the spaces between
the burners, so lots of oil and molten fat ends up on these unprotected spaces.
