Sadly returning this.  The handles won't stay tight and the screws that hold them are already rusting. Plus hard to get it up to pressure - too much sputtering around the handle for a long time!  I remember my Mother cooking delicious tender meats in her pressure cooker years ago.  But I did not have good results with this one. Followed directions and chicken came out tough.  And - a magnet won't stick to the interior (only the exterior)...so maybe the interior is not stainless steel, but aluminum..which is not what I want to cook my food in. Thank goodness for Amazon's return policy.
