once I got past step. 2, assembly was a breeze. The bottom and top half post covers were a snug fit over the 4x4 post.  I had a bit of trouble getting the top sleeve to telescope over the bottom sleeve as shown in the picture.  Didn't want to force it.  Took a couple taps on the top point with a rubber mallet and it slid right over. From that point on it was easy.

Cons: need a rubber mallet if you get stuck
