I bought the main composter and two "add on" composter sets so I could create a 3 bin compost set.  These sets were very easy to set up.  You can set it up with only one person--I did it by myself. It did take a little wiggling back and forth to get the slats to move down in unison so having a mallet to do this helps. Unfortunately, I didn't have a mallet so I used the back of a screwdriver which worked fine. I am very happy with this product and highly recommend it to others!
