We purchased this composting system from Costco a few years back, and tried to make it work, but turns out these need a lot more green stuff, like grass or leaves, to actually work; stuff we just didn't have.
We finally gave up. We emptied it, then disassembled it and hosed & scrubbed it clean.
It is all sitting on our deck table outside, hoping someone can use it. It's all still in very good condition, and comes with an added hose we used to catch the liquid "gold" that these things produce. Instructions that came with this are included, as seen in photos.
