I love this composter idea because the bin is mostly underground. I love compost for my garden but really don’t like the look of compost bins. I have a corner spot in my garden where we have a compost pile instead of a bin but it takes a lot longer to make compost because it can’t maintain the heat to break it down fast. This would work well and I could put two in that corner so I could be filling one whil the other was composting and since only about 15 inches are above ground I wouldn’t have to see the bins and it would keep the critters out.
