Saw these mentioned on another thread and am seriously tempted to buy one. We compost raw kitchen waste at the moment. Cooked waste goes in our brown bin, along with garden rubbish, which the council collects fortnightly but it is starting to smell bad in the heat (even though I wrap all food waste in newspaper). I like the sound of being able to compost all kitchen waste myself. Does anyone have any experience of these systems? What maintenance do they require? How quickly do they fill up? Do you get any smell at all?
