In my 68 years of cooking, I have worn out 3 pressure cookers, all stovetop models. Love my pressure cooker especially, as has already been noted, for saving time in the kitchen.
My first one was a good old workhorse of a Presto. The second was a fantastic Revere Ware one that I had to give up because gaskets were no longer available, but I did use it for a long time as a great heavy-duty pot with a Revere lid from another piece of Revere Ware I had.
This last one, in my estimation, is the cream of the crop. It's a Kuhn Rikon and it came with the standard large pot, along with a much shallower one for smaller quantities of food. I've used the bejeepers out of it and, at my age, I have no doubt it will be my last one.
Never had any accidents, blow-ups, etc. with any of my pressure cookers, but my mother did when I was in my teens.
She prepared a recipe of green split pea soup and allowed the vent to clog. We had a beautious green explosion and the kitchen was never the same again.
