Just had through my latest copy of Kitchen Garden and they have reviewed 13 composters. The beehive composter from WW comes out as pick of the bunch as the best looker and among the smaller bins the CompostBox came out as one of the clear winners.
Interestingly they talk about the best way of making compost as piling it all up in the bin and waiting. This is all well and good but in my experience adding waste gradually is much more practical and as long as you add plenty of carbon in the form of cardboard composting making is easy. Worms will help aerate and speed the process up, and of course they will reduce the volume meaning you can add more waste.
