Product review (3 stars): drip pans
They all fit perfectly.  But i did have a problem with one of the larger ones.  It got bent/dented somehow when i used my cast iron pots with it.  Maybe not enough clearance at the bottom???  So it's all chipped along the small inner circle and probably won't last very long before it rusts out.  Could have been a bit more sturdy, and willing to pay a bit more for more durable goods.
