Title: Bad Engineering
Review: This is the third pressure cooker I've owned, the most expensive and the absolute worst. The locking mechanism was apparently designed in a kindergarten. It continually leaks and fails to build up pressure. I've had to shut it off, release the pressure, remove the lid, replace the lid and restart the cooking. Today even that did not work. And if you're not careful the locking mechanism will jam and prevent the lid from rotating into position.This is the last product from Presto I will ever buy!
