It seems these kinds of canopies in the stores are flimsy when shaken, but this one is standing firm.  We get some strong winds on our deck and it is holding up well.  We screwed it down to the deck with the intention of also using tie downs to the railing to reduce sway but we don't have to.  

Pros: Great value, good quality, expecting to get two or three years use out of it.
Cons: Was missing a couple of nuts for the screws but found some other matched screws/nuts in the shop.
