If you're looking for an inexpensive composting solution, the Compost Wizard Standing Bin is the answer. Made of light, durable plastic, this unit is easily set up, but can take mother nature's abuse. The attractive ribbed design helps with aeration while reinforcing the structure. Aeration vents located around the outside are too small for rodents and other animals to get through. Both the top lid and lower access hatch are large and have easy-to-grip hand holds for convenient access. The whole unit ships conveniently in two interlocking pieces. Setup takes about 5 minutes and is as simple as securing the top to the bottom. During setup, you can also configure which side you want the bottom hatch on.
