I’ve got two compost tumblers. The first one is way too big and even my 6’2” tall spouse can’t turn it when it gets more than 1/2 full. So we bought a second one that has two smaller bins. They both work fine. But I have to say that the old fashioned bins I made many years ago from hardware cloth (also called rat wire) and 1x2 boards works just as well. We use those for leaves and other garden waste and that compost is used when we want to make new beds.
