We are new owners of the dual drum composter. We will revisit the review section next spring, after it has been tumbling and digesting for the winter, to assess the quality of the soil production and how well the mec. We generate  low volumes of household scraps so we generally need to augment with carbon-rich material such as sawdust. We also inoculate when necessary to punch up the biota. We transferred our two heaps to the drums a week ago and have spun them twice. The frame seems like it will last the life of the drums. Our only concern is how much mass this unit can support and contain. Not only would the axial pipe begin to flex in the middle , the drums become impossible to turn.
