A bit complicated to build. When we were putting it up, one of the legs fell and the soldering snapped pretty easily. 
We were able to fix it with metal screws and it's probably more solid than before. I recommend having 5 people to put it up, as we had 4 and it was still difficult.
One issue we have is the bars that the canopy clips on bend out all the time. We made sure the legs were straight and level and still have the issue. As well, keep in mind that high winds and rain will blow it around and make it sag and not look very nice. Can get a bit tedious fixing this all the time.
It works for us though, and generally I like the way it looks compared to a regular gazebo.
