I had JOBO make me two polycarbonate inserts for JOBO print drums while they were available. One for 11x14 and another for 12x20 and only used each about twice. The reason was simply because it took so much time to develop each sheet of film and efficiency was paramount to me in my quest to make photographs. Many of us have families and full time jobs so we do not have unlimited time to spend in the darkroom.

I would be lucky to get two processed with the inserts in that time and while the inserts would certainly do a good job, the trays accomplished the stated objective every bit as well.
At the end of the day it is about accomplishing the objective of making photographs and as we all know there are many diverse ways to get this done.
