We love this Pergola.  It was easy to put together and looks lovely on our deck.  I only gave it 4 stars because two of the posts had dents on delivery.  One was much bigger than the other.  We put the bigger one toward the back but the other is at the front. Overall, though, we are happy with it. The canopy slides easily up and down and you can also slide it way back out of the way. There are several ties that you can use if you want to secure it on a windy day.  We haven’t found it necessary.  There are 4 screws on each foot to screw it securely to the deck and there also are cover sleeves for over top to hide them.  I would recommend this product.
