I have 2 of these composters, giving me 4. I like having 2 so you can start one and then work an another when that one is full so you can keep composting. I put i grass clippings, leaves, kitchen scraps and even a little dirt to keep it going. I found that oak leaves don't compost well so brake them up if you use them. I also found that keeping it moist made it work a lot faster. I would add water to it weekly if it got to dry and it would compost a lot faster. Setting it up was a bit of a chore but they are solid and work well. I have used them for a year and half and I got some really good compost. It does take time though. It took me about 6 months. If I had known to keep it moist I could have done it faster. It's been nice not to waste my grass clipping and kitchen scraps and leaves in the garbage. I'm getting good soil and it's rewarding.
