Product review (5 stars): Love this radiant cartridge
I love this cartridge.  I've had the "regular" burners before but like these better.  They are easier to keep clean.  While they are hot for a while, I don't have small children and they cooled down faster than I expected.  I was in a hurry to get these as my old burners had were just that -- old and had ceased to function well.  The supplier got that cartridge to me in just two days, too.
