I have 4 of these bins which I give to friends. They use them and I get them back when they are full so saving landfill and boosting my compost bulk! I have tried them at home to see how they work and must say they do smell when you take the lid off but the smell doesn’t linger too long. You use the impregnated bran and they give off a liquid which canbe used (suitably diluted) as liquid fertiliser or to clean drains but most usefully can be used sparingly instead of the bran as it contains the right bacteria to keep the process going.
If you get the bins and then decide not to use them the best use I have found for them is to put comfrey leaves and/or nettles in to make liquid fertiliser. Certainly worth a try. Some people swear by them, others hate them.
