We installed this pergola onto our slab patio. Putting it together was rather straight forward and easy for two people. It looks great and has already stood up to high winds. Its certainly not the same as a wooden pergola, but Im excited that it will be low maintenance for the years to come. The only issue we had was the caps that cover the upper most holes kept falling out. They do not mesh up properly at all, so we decided to caulk them in and that solved the issue. Overall, we are happy with this purchase, especially considering the price.
