this is a wonderful cooker.  The size is great for 2 or 3 people but I would get a larger one for more people.  Everything comes out tasty and the meat are tender in such a short time.  The only problems I had were in the beginning.  I thought you needed to keep the pressure regulator jiggling to cook the food but if you do that the heat is too high and it burns the food so turn the heat down once it starts jiggling.  Also be careful when you wash the lid.  If the pressure plug gets caught the steam escapes and you think the cookers not working and the food will burn because you cook it too long or have the heat up too high.
