I have this composter chosen because I can expand it if necessary. With the supply everything worked out well. The building turned out to be very complicated. You have the clips at the corners that hold the side panels, click on those recesses. Major small and narrow space is hardly that. When one is then finally made and the composter is, he wobbles just back and forth. He is very unstable. We have filled in, so he has some fortitude. Despite complaining of above, the lid always flies on, the composter shifts in position. At the slightest wind can even fly (luckily he has a neighbor no harm done). Therefore, this unit gets from me only one star, because as purchased so discarded.
