Product review (5 stars): Works well.
I bought these when I bought replacement burner pans for the stove. We've had them on for about three months, and they're still presentable. I don't think that you would clean these and put them back on, they're too fragile, but they protect the burner. It only protects the inside, however, the lip that rests on the stove top is NOT protected by the bib. So for the price, and not having to regularly scrub the burner pan or doing a similar but tacky job with foil, these are well worth the purchase. They do only fit two of the four burners on my stove, but I'll be able to replace them again without ordering more, so that didn't really bother me.
