We haven't used it yet, but we're so glad to see that Sonia at Unplggd has one and is reviewing it in installments!
She's done two installments on her experience with the Naturemill composter and so far it sounds great! She gives very detailed explanations of how she had to set up the machine and how it's working now, a couple weeks into it.
Check out her posts here, at our sister home technology site Unplggd:
Also, stay tuned - we'll have our own review and thoughts on this machine soon! My fiance and I actually registered for one of these puppies (our registry list is super short - this is the thing we're most excited about, to the amusement of friends and family) and someone bought it for us. We have a Naturemill composter coming soon and we can hardly wait to get started!
