Product review (3 stars): Very model-specific
These burner bibs work well, as long as you use them with the stove for which they are designed.  They are NOT generic, and have small notches cut in them to fit the burner grate.  I wound up having to take some tin snips and widen these notches to allow me to reassemble my stove, since otherwise the grate does not sit flat or fit into the hole on the stovetop.

They work, after the modification.
