Great, well built gazebo. Assembly is a bit of a challenge, but a bit of planning and laying out of the major parts before you start can easily help. Installing the primary roof panels will make a preacher swear. I ended up using a long, round screwdriver shaft, inserted into the roof mounting holes of each panel, in order to maneuver and line up the other holes in the panel with their support holes. The "Z" clips that go on the top of each roof panel are practically useless as they easily fall off unless duct taped on. Even with those install headaches, I'd easily buy this gazebo again. Very sturdy and looks amazing when complete! Also, be sure to search for videos on YouTube from others that have installed this one and similar models. Those videos helped me the most during assembly.
