We have had a pressure cook for many years.  It was great for camping, for we could make New England Boiled Dinners.  My wife has our old one at the shore, and we use it a lot.  However, many of the family are not there but in our villa 100 miles away, and we like many meals that we us the Presto pressure cooker.  Now, I can make the dinners here, and we think they are the best pressure cookers around.  It is great time saver  Well we made a mistake and I believe we did not have enough water and we got a convexed bottom on the old one  So it had to go. We now have another new one.
