So glad I went with the stainless steel.. I have used pressure cookers for years.  Quick for cooking cheaper cuts of meat and cooks fresh green beans to prefection.  This one has been easy to use and clean up is a breeze.  I Purchased this one to replace one that I  had used for many years. And happy that I did!  Remember to read the directions and the cook book carefully and problems will be avoided.  Very easy!
