Product review (4 stars): Perfect from a cleanup perspective
I like these.  The other replacement drip pans I've bought in the past have been very cheaply constructed and with a rough surface that just holds onto spilled food and looks filthy in short order.  These?  The smooth porcelain finish means I can wipe them clean in a flash.  I've also put one of them through a dishwasher cycle without any damage.  I would have given them five stars, but the cutouts meant to accept the supports for the burners don't align with the supports on the two larger ones.  I can do some 'gentle persuasion' and get them to fit, but it's not ideal - there's a bit of a tussle to re-align them after cleaning.
