It took my wife and I two full days to assemble.  There are alot of screws-)  The Gazebo seems well made and it was well packed.  As far as the instructions go I give them a C.  Adequate but not great.  I would suggest you head to youtube to find an assembly video to at least see it first hand.  SUGGESTIONS  Cordless drill with a hex bit is a must.  You will need at least two people to erect the structure but three is better.
 We are super excited about our new Gazebo.  It looks like the two days was worth it !!! Time will tell.
