I have a OBS: dual probe PID, 900w finned element, and a oven convection fan mod.
I mainly use it for smoking salmon, cheese, and jerky. Anything that needs cold smoking or tight temp control.
I had to re-enforce the door with a new hinge & plate and make a new front plate. The plastic does not seem to react to the heat well. Other than that I am happy with it's performance.
