Do Tumbling Composters Really Make Compost in 14 Days?

In my experience, tumbling composters overpromise. In winter they cool too much for active decomposition; in summer they dry out too fast. The simplest, most reliable method: layer kitchen scraps with leaves in an open pile. If wildlife is a concern, build a 12-inch diameter cylinder from ½-inch hardware cloth with a lid, and sink it into a leaf pile. Or dig a 12″×12″ hole, cover with a concrete paver, and toss scraps in. Low-tech works.
