Well written review!
A tip on infusing, when the infuse cycle is finished and it's cooling down. pull and filter as soon as you can. You can recover more oil the warmer the material.
You can clean up the oil by placing a coffee filter over the French press plunger/filter part while first filtering or afterwards.
When doing large batches, like recovering goodness from worked dry ice hash material, you reuse the oil from one infuse cycle for next. It will just add potentcy.
