The Compost Wizard Eco Tumbler is an affordable composter with some great features. Sized to accommodate the needs of a small to average sized garden, Because they are separated, you can run batches independently, getting compost even faster than a single batch tumbler. Because of the smooth turning and tumbling action, the compost material can break down into earthy hummus in as little as 30 days. Aeration is strategically located along the outsides of the bin to allow optimal airflow with minimal mess. While it's easy for you, it's not easy for critters to get in. The low odor design is also very tough and can stand up to weather and moderate impacts. The hand holds are great for gripping and also provide agitation for the material inside, breaking up material. Some assembly required.
