This product was actually fun to put together.  It is very well made and works efficiently.  I actually purchased it to mix three types of gravel together rather than for composting.  It made the job quick and easy.  Even though I was dealing with small rock, which you might think would ruin this composter, once I finished the job and rinsed it off with a hose, it looked brand new.  The only thing I have some reservations about is the sliding door on the composter. I would have preferred a separate door for each side of the composter.
