This product was recommended to me by someone who also uses a Presto pressure canner. I have been very plesed with the product. It was delivered in a timely manner. Instructions are included with the product that are easy to follow. The instruction manual also includes directions for canning specific fruits and vegetables, information about canning utensils and proper canning supplies. This size canner will process a 7 quart volume at a time. For a novis canner like myself this product was a perfect choice.
