Product review (5 stars): Nice looking, easy to clean
These are nice looking, easy to clean, and fit our 30 yr old Whirlpool perfectly.  I feel lucky to have found this set of 3 - 6in" and 1 - 8in" drip pans sold as a set.  Saved some money over buying individual pans to match our stove top burners.  I read one review saying the metal was thinner then the same product available at their local store.  I didn't check with local stores, so can't compare, but these are thick enough to be rigid, and do not flex when twisted.  They are definitely more sturdy than the chrome OEM they replaced.
Drip pans typically provide two functions.  They catch spills from pans boiling over, and they are usually made of reflective material to make stove top cooking more efficient by focusing radiant heat back toward the cooking pan bottom.  These being black, don't offer the same reflectivity a chrome pan would, but my girlfriend uses the pot boiling over to know when the food is ready, so chrome drip pans only stay shiny at our house for a few weeks at most anyway.  I'm very happy with this purchase.
