Compost Wizard 5.7 Cubic Foot Eco Tumbler, Black 

An affordable composter with great features, the Compost Wizard Eco Tumbler has dual chambers that hold up to 5.7 cubic feet (42 gallons). Because the chambers are separated, you can run batches independently, getting compost faster than a single batch tumbler. With smooth turning and tumbling action, the compost material breaks down into earthy hummus in as few as 30 days.

Aeration is strategically located along the outsides of the bin to allow optimal airflow with minimal mess. The sliding door has no moving parts and can be pushed to the side to open. While it's easy for you, it's not easy for critters to get into. The low odor design can stand up to weather and moderate impacts. The coated, tubular frame is able to support a fully loaded composter with ease. Hand holds are great for gripping and also provide agitation for the material inside, breaking up material. Best of all, the bin is made of 100% recycled plastic. Some assembly required.
