I have used one, as did my mom.
Do take comfort though, Ronni, todays versions have come a long way and are miles safer than yesteryears versions.
Modern pressure cookers have auto-valves, locking lids, and some even come with manual safety release valves.
Nevertheless, there's good reason to be fearful of the thought of a pressure cooker pot exploding, because they have and do, and the end result can range from severe burns, to amputations, blindness, concussions, broken bones, disfigurement, even death.
My advice to any/all who are looking to invest in pressure cooker, don't cheap out.
