Tumbling mulcher is sturdy using thick material and good quality steel nuts & bolts. It is much sturdier that one that i previously bought that is held together with clips. Legs are painted so they won't rust out soon.

My only criticism is that the overall size is kind of small. The doors slide well. Make sure that the tabs fit together completely for the connections above and below the panel containing the openings.

The composter is sturdy and easy to spin. Rotating or mixing the compost is simple and easy. The chambers are spacious and in spins very easily in both directions.

Pulling springtime weeds from my large (not huge) suburban lawn completely filled one side of the composter. It could even be used in an apartment setting with a patio.

The setup is not difficult; just 56 bolts and nuts have to be aligned. The bolts are a bit tedious but once you get a system going they really go fast.

The divider is 1/8 too small to reach the track on the opposing side when set flush. The holes in the leg tubes were drilled out incorrectly and could not be assembled. And when i spin it, the water sprays everywhere.
