Overview
Turning the hexagonal drum mixes the contents of two separate chambers, each with its own sliding door, so one side can be loaded while the other finishes. The body is alloy steel and black.
Two chambers are the reason to buy, since a finished batch does not have to wait on fresh scraps. A sealed tumbler is neater than an open pile, though the listing says nothing about aeration or pest resistance.
Who it's for
A household composting kitchen and light yard waste in a small outdoor space. Someone with large volumes should look at a bigger bin or open system.
Pros and cons
- Two chambers for staggered batches
- Sliding doors for loading
- Easy-turn tumbling action
- Hexagonal drum rolls to mix
- Assembly details not listed
- Total capacity modest for big yards
- Aeration and pest features unlisted
Performance notes
Tumbling mixes air into the pile and moves moist and dry material together, which is what speeds decomposition. Separating the load into two chambers lets one batch rest undisturbed while the other fills. Results still depend on the balance of green and brown scraps and on moisture.
