I bought this to replace an Aluminum Presto pressure cooker that was made in 1941 and still working, but I wanted a stainless steel one.  I love this new one.  The recipe book is a huge help because it lets you know whether, or not, to let it cool down on it's own or to cool it immediately under cold running water and it has a time table with quantities that serves as a guide.  Once the pressure regulator starts rocking, it only takes 10 minutes to cook a 5lb pork roast and that means no created heat in the kitchen which I especially appreciate in the summer.  You do have to brown roasts first, but they melt in your mouth.  I did find that artichokes took 5 more minutes than stated in the book, but that's still really fast.  The stainless steel cleans up very easily, especially if you soak it for a few minutes.  I highly recommend it!
