I have used other versions of this Presto stainless 6 quart pressure cooker for year. This time the cooker came disassembled and I had to screw on all the handles (3: 2 on cooker, one on lid.)  EVERY time I use it I have to tighten the handle screw.  EVERY SINGLE TIME.  This cooker is no longer the top quality item I have purchased from Presto in the past.  Avoid this product.
