We've used dozens of composters over the years, and have incorporated all the features we like best into the Deluxe Pyramid Composter. The lid is hinged so you can open it with one hand, yet it can't blow away. Narrow side vents ensure good ventilation. Two sliding doors, front and back, stay open to make removing compost easy. Best of all, the signature self-watering lid lets in the right amount of rainwater for optimum performance. Convenience and large capacity at a great low price! Holds 12 cubic feet.
