Product review (5 stars): Good product for the price
These burner covers are just what we needed.  We wanted something to cover the other burners while we cook in order to keep them clean.  These covers did the job.  It's ridiculous to expect them to hold up if you turn the fire on underneath them.  However, they are doing well even when the edges are near the lit burner.  They are no weaker or stronger than the lids you find on cookie tins.  The price is reasonable as well.
