My husband gave me three of these composters (Achla CMP-01 Plastic Tumbling Compost Mixer) about ten years ago as he thought they were more attractive than my bins. I can’t make compost with them unless I use an activator, which is not the case with my stationary bins. I don’t like the fact that the way to make compost in them depends on my having all the materials handy and doing it all in a single batch. This doesn’t fit our lifestyle. The tumblers don’t facilitate decomposition unless they are mostly full — if not full enough, the materials inside just dry out instead of decomposing. When the tumblers are sufficiently filled to allow for decomposition, they are almost too heavy to turn. When I do turn them, they emit a sewer-like odor — which is not the case when I turn my stationary composts. It is difficult to empty the composter as the opening is smaller than the widest dimension of the sphere and the materials plug up the opening. The only thing to do is to turn the composter upside down without the lid on in an effort to dump it out on the ground and bend over using a hand trowel to try to undo the plug. Very awkward. If I can get the finished product to come out, I end up with a pile that is so tall that the tumbler is stuck in the upside down position. I then have to slide the composter to the side to continue emptying it and eventually shovel the end product into a wheelbarrow. Moving the composter is inconvenient as the metal legs come apart and I end up repeatedly putting the composter legs back together every few feet.
