Product review (5 stars): Exactly what I needed!
I'm so glad I found this again.  I've been using this product for years and thought I wouldn't be able to find it again. I'm restocking my stash so I don't run out. The product lasts a reasonably long time, and if you cut the center portion large enough to fit your gas burners properly, it won't burn. It works perfectly with my modern gas range.
