I've been using an ancient 4-quart Presto pressure cooker I inherited from my mother. The old one was probably made in the 60s, or before. They last almost forever. But I burned some food and couldn't get the old one clean, so I got this replacement. It's lighter and easier to handle. With occasional gasket replacement, I assume it will last the rest of my life. The booklet that comes with it is small but useful, listing cooking times for common dishes.
