I give 5 stars to both Wayfair and Sunjoy.  Wayfair delivered the Gazebo when promised and the delivery man helped take the box to my back yard.  Assembly was straight forward, some modifications needed in instructions, and easy.  Every part fit exactly right and all bolts and nuts fit perfectly.  What I thought would be a long time assembling only took 1 day.  Now to the instructions.  They are only pictures which were easy to follow but on a few instructions it should have mentioned to leave bolts loose.
