I love a good 'ol fashioned pressure cooker. When my 40+ year old Presto recently gave up the ghost, I knew I had to get another. Sometimes, I might not use it but 4 or 5 times in a year, but it's one of those kitchen tools that when you need it--YOU NEED IT. This new Presto works fine, the problem is the assembly screws. I don't know what it takes to get these screws tightened enough to hold, but whatever it is, I don't seem to have. The result is that the handles wobble and the connection between pot and lid is compromised. Not sure what to do to resolve this. I'm winding up re-tightening my screws every time I use this. What a hassle!
