Product review (5 stars): Found them just in time!
At first I hesitated to buy 45 of them at once, but since they have become unavailable where I live, I went for it.  I'm glad I did since they are every bit as good as the ones I can't get any more, at a comparable price and delivered to my door, what's not to like..  There's nothing worse to clean than the grunge on a gas range and these keep it off very well.
