Between the two of us, Steve and I have done a pretty good job of turning/rolling the bin at least three times a week. Unfortunately, our £7.50 RollMix Composter doesn't seem to be able to withstand even two months of that kind of use. There's a springy wire that wraps around the outside of the cylinder to help hold its shape, and the end of that wire popped out within about two weeks of use. After three or four weeks, the casing for that wire started to rip around the middle. At this point, I just hope that the bag itself lasts long enough for us to decide whether or not a big, rigid compost tumbler on a frame is worth the investment.

Frequent turning of the pile is supposed to help create a better oxygenated environment for the aerobic bacteria that do the heavy lifting in the initial stage of composting, but those bacteria also need heat, which is in short supply this time of year. As I'm typing this, the weather guy on the radio is going on at some length about the "Beast from the East" bringing icy weather from Russia and making this the coldest February in some large number of years, so our local population of decomposers is working at a serious disadvantage.
Whether or not the tumbling action has made a significant difference, there can be no doubt that the composition of the pile has a huge effect on the behavior of the compost.
