Gazebo went up in a day  and a half , we are very happy with it. They provide some extra screws,   parts which come in handy if you lose any during the build.
A cordless drill will speed things up significantly. I did receive some bent roof panels but straightened the parts out with pliers,  theyre not seen in the final stage. All in all this gazebo is solid   is staying put , it really is a great addition to the deck . I highly recommend this line of gazebos .
