The 220 l barrel is resting on those small 4 wheels, so that turning it just takes a few seconds, and inside there are 2 half pvc tubes to help mixing.
It is my first compost tumbler, so we'll see how it goes. My main concern is that it reaches the critical mass needed to trigger the composting process, and that is doesn't take long (I need quick compost).
Meanwhile it looks good, and using it is really so easy that even my 9 yo brother can do it!
