Product review (5 stars): Strong and durable
This product is great.  I bought one for myself and my parents also bought one.  It is heavy duty and does not bend or break the element when canning and is able to support the weight of the canner.  I forgot to remove it after canning and discovered that it heats up and boils water much faster than a regular burner.  Fits into stoves as it claims and I would think it came with the stove if I did not know any better.
