The gazebo frame is standard quality with a few upgrades for rigidity. The cover, mosquito netting and drapes are excellent quality.
The instructions are useless. I've assembled several similar gazebos and you are guaranteed to have to go back and change part of the assembly since part of the process will be a guess on your part.
The canopy is next to impossible to install. Remove the plastic ends on the struts and be prepared to use serious force to get the struts into the pockets. The last pocket on the large canopy required a pair of vice grips, a long rope, tying the upright to a post and all the pull my wife could muster while I pushed from the top.
The finished product is worth the effort if you can manage it.
