First of all what a great and necessary addition to our west facing deck in Texas.  It’s a great look and I added Coolaroo sun shades to two sides so we are shaded from the setting sun lower on the horizon.  
Really cannot beat the $400 price point.  Easy to assemble as long as you follow the instructions.  Key point: only hand tightened all screws until completely done-then tighten everything down firm. Everything fit perfectly as instructed and I assembled nearly all by myself.  I did have my wife and daughter hold the two long sides while I attached the cross rails (that took 15 minutes maximum.) Warning : it is made from very thin aluminum and there is a good chance some part (probably a post) will arrive with a dent.  I opened the box while fed ex was still there so he could document it as damaged.  I had one dent about an inch to inch and a half in diameter that was not structurally significant and not seen.
