Is this " power pressure cooker" the same as the old fashioned pressure cooker on the cooking stove type, except it is electric?..... I went on line to check it out......also read reviews...more negs than pos.....I have the old fashioned PC...learned to use it from parents who had one. I don't use weekly...just certain things, times of year....just like my crockpot..only use it occasionally........some things I can cook faster, more efficiently on stove rather in " pot".... That's just me.......
