Input:
I had a very heavy aluminum electric pressure cooker.  I bought this one because it was lighter.  It works great.  Since I have a new stove with a very high  burner, BTU the water heats very quickly so the cooking time is short.  It was a good value even though the aluminum discolors from certain food cooked in the pan.
