This tumbling insulated composter really cooks. I recommend it in spite of the price. Mine sits in the sun and works year-round. It's fast, and the finished compost is excellent. I use shredded oak leaves as the primary carbon source, and the only nitrogen comes from kitchen waste. The composter has enough room to easily handle the kitchen waste of our family of four. It could handle more, I think, maybe twice as much. In summer, the BSF larvae love the heat, and really crank up the decomposition. As a result, I haven't seen any other species of pest in or around it. The only complaint I might have is that the insulation in the door has shrunk enough with the heat that it sometimes is dislodged. It should probably have some aluminum straps or plastic fasteners to hold it to the door.
