There is a bit of a flaw in the instructions for installing the pressure cooker cover; it reads "Install the Pressure Cooking Cover, by alingning and inserting tab into slot." With no mention of the hole the tab needs to go into behide the slot ing the locking ring. This is only a problem when you wife doesn't see said hole and then she hulks the cover into place making impossible to close the lid or remove the cover from the lid without the use of extreme blunt force trauma. If anyone has a way to fix this in a more delicate manor then the application of explosives please let me know.
