I'd give this 5 stars if not for the roof assembly. Absolutely horriffic. The clips (Part Z) do not stay on while being moved around during fitment.
We wound up caulking them in place. They HAVE to figure a way out of this. Shouldn't be too hard.

OK, enough bad. Now for the good. I would absolutely recommend this gazebo. It's quite a sturdy piece of construction. We put a fan on the ceiling and it works great. Next we'll get some lighting and that should do it. Again, it's a terrific addition to our deck. I used Ledger Lok lag bolts to attach it to the deck. It took the 2 of us (me 69, wife 67) old crones about 16 hours (4 days , 4 hrs. each) to assemble it. We worked slowly and took a lot of breaks. If we can do it, anyone can. 
In sum, if you're on the fence about this, put your mind at rest. It's well worth it. Go for it.
