Amidst a sea of expensive planter boxes, this maintenance-free planter box is a fantastic stand-out!  I am happy with pretty much everything about it!  While the instruction diagrams aren't the easiest to understand, each piece is numbered sequentially to ensure you're putting together the correct pieces which is a tremendous help. Once I got the hang of it, it was The only reason for rating this as only 4 stars is because the upper end pieces wouldn't fit in their slots.  So after putting quite a bit of muscle into it to no avail, I got out some sand paper and sanded off a little bit of the edges of the slots, which then allowed the pieces to go in.  Just a relatively small hiccup in the overall process.  

Pros: Durable, affordable
