This was not easy to assemble, especially when screwing the long panels to the octagon sides.  I can see where there are tiny gaps where the metal is not flush with the sides and eventually the 'compost tea' is going to leak out of these gaps .  Other than that, it is sturdy and balanced .  We set it outside in the bitter cold, added our first batch of kitchen compost and the next day, even though the over night temps were freezing , non of the compost inside was. 

My only other issue so far is that when you flip one lid open, to add compost, the unit wants to spin backwards, so I have to use one hand to hold it from tipping and the other hand to dump in compost. 

I do like that I bought a composted with 2 sides so we can be continually making fresh dirt !
