Product review (4 stars): Supports a fully loaded canner with ease!
I purchased 2 canning burners after my canning season was almost over.  After I received the canning burners I was wishing I had them earlier in the season.  A full canner on my old burners caused them to buckle and be uneven.  The TRUE canning burners solved that problem.  I would recommend them for anyone who cans on an electric stove.
