We got this composter kind of late in the season (October). It's meant to be used in warmer weather to do it's job properly, so for now it's not composting quickly as it should. I'm hoping when spring / summer comes it'll do its job properly. I was hoping it would hold more than what it does, however I did put some bigger brush / weed type plants into it to start and I know that it does take some time for them to break down. Also the lid is a screw on type with threads and it's every easy to cross-thread it when putting the lid back on and any dirt or debris that falls onto the threads when putting composting material into the composter can cause the lid to not screw on properly too. It does tumble and spin properly if on level ground. Therefore for the capacity and cross-threading of the lid I gave this composter 4 stars.
