Since I have a lot of cameras, they tend to be used only a few times over a very long period of time. One camera that I used intensely though was an Edixa Prismaflex which I was constantly running film through from 2012 through 2016. I ran Agfa Precisa through it, almost exclusively, and when that film was discontinued I stopped using it. Its last real outing was when I took it with me to Japan and it developed a front-focusing issue, so now it's on the shelf.
I still have five or six rolls of Precisa I need to drop off...
