Yimby Tumbler
This is the tumbler I have used longest. Dual chambers mean one side is cooking while the other side accepts new scraps. Eight-sided drum tumbles easily even when full. I get finished compost in about 5 weeks during summer.
I have composted in my backyard for over a decade and have tested rotating tumblers to find ones that actually break down material in weeks, not months.
I keep a kitchen scrap bin going year round and I cannot stand the smell and bugs of a pile composter, so I switched to tumblers years ago. After running five different rotating bins through real seasons, these are the ones I would buy again.

The picks, reviewed
Yimby Tumbler
This is the tumbler I have used longest. Dual chambers mean one side is cooking while the other side accepts new scraps. Eight-sided drum tumbles easily even when full. I get finished compost in about 5 weeks during summer.
FCMP IM4000 Outdoor
The FCMP is almost the same size and shape as the Yimby but feels a touch sturdier in build quality. Same dual-chamber design, same easy turning. Comes preassembled more thoroughly than the Yimby, which saves 30 minutes during initial setup.
Lifetime 65 Gallon
The 65 gallon is for big families or serious vegetable gardeners. It holds nearly double the volume of standard tumblers. Single chamber means you have to time your batches, but the throughput is the best of the lineup.
Spin Bin Single Chamber
The Spin Bin uses a vertical-axis design instead of horizontal. The unique shape means it fits in a narrower footprint, useful for tight yards or patios. Single chamber works best for continuous batches if you stop adding to one end and let it finish.
Miracle-Gro Dual Chamber
For small yards and patios, the Miracle-Gro is the smallest dual-chamber unit that still produces meaningful compost. 27.7 gallons total means you get enough for a 4 by 8 raised bed each cycle. Easy to assemble in under an hour.
FAQs
With proper greens-to-browns ratio and regular tumbling, you can get usable compost in 3 to 6 weeks. Without aeration, the same materials in a pile take 4 to 9 months.
Much less than pile composters. The sealed, elevated design and the tumbling action keep rats and mice out. I have not had a rodent issue in 8 years of tumbler composting.
