I have owned Presto Pressure Cookers for over 40 years and wouldn't be without one. My mother and grandmother also used them throughout their lives. Pressure cookers save time in cooking and food comes out tasty and tender. I have used other brands, but keep coming back to the Presto. Their quality has remained superb with each model change. I highly recommend them. The 6 quart size is good for larger families and meals. For small meals or a couple with no children, the 4 quart is perfect. I have both sizes.
