Very disappointed in the quality of the pergola for the price.  The metal is thin and the canopy is a solid plastic like material that doesn't let a strong wind pass through as a result the wind will surely take the entire unit for a walk at the least and will most likely bend the metal.  This is really disappointing because I bought one 4 years ago and it is 10x better made and I paid $300 less. Also, there were not enough screws/bolts included in the package and we are having a hard time getting what we need to complete the construction.
