This won't say I am a verified purchaser, but I've had this cooker for over 20 years.  Tonight my wife gave it a drop test that pushed the jiggler stem through the lid.  I could fix it, but I'm not even going to try!  I respect the power of steam too much!  Lesson:  Do not drop pressure cookers inverted on ceramic tile floors.  (Fortunately, it didn't damage the tiles!)
