Strong words for a pressure cooker, I know, but this thing has been such a disappointment.  I bought it to replace my old 6-Quart Presto pressure cooker that worked well and faithfully for many years.  I'm not sure if they have started making these things in China after I purchased my last pressure cooker or what.  This new one is much lighter weight and the metal feels thin and cheap.  The handle screw continually comes loose which makes the handle itself loose and wobbly.  The pressure hole doesn't seem to line up properly so that I have to use a knife to wiggle the pressure button free to pop up so it can start to cook after the pressure builds.  If you are looking for a solid, reliable pressure cooker - - keep looking!  This is not the one!
