Mom and Dad used to use a pressure cooker a lot until the occurrence of The Great Exploding Chicken beset us. Mom's cooking a whole chicken in the pressure cooker, and something went wrong because the emergency check valve blew-and so did the entire chicken bones and all right through the pencil-sized check valve hole.
The check valve blew with such force, it went through the sheetrock ceiling and up into the attic somewhere. The entire carcass blew through that little hole. We had chicken piece/parts from one end of the kitchen to the other. Bone fragments were actually stuck in the sheetrock. Talk about a mess. Had anyone been standing there at the time they would have been scalded and possible worse. We never used a pressure cooker again.
That is why I plan to go American-made, from this place....even if it is made in Wisconsin.
