I bought the 8 quart cooker. This is a wonderful, simple to use pressure cooker. It  holds 7 pints when using it for canning. Quart jars will fit in it, and I suspect it would hold 5 of them though I am not sure. Comes with the rack that sets on the bottom to keep Jars off the stove. The pressure valve that sets on the top is different than what I am used to because I have always had the adjustable kind- 5, 10 and 15lbs of pressure. This one says it is preset but I cant find any information about what it is preset to! None the less it canned my green beans wonderfully, and I cannot wait until I fix my Irish corned beef and cabbage in it. If you need a pressure cooker, quit looking because you have found it!!!
