The Pergola is very nice. It will take two people with six foot ladders to assemble in about 3 or 4 hours. I had a few issues with it, the aluminum base only has two pre drilled holes, it should have have four to balance the weight all around. After you screw in the bolts you have visable unsightly screw holes you must look at. A boot cap would have also been nice to cover the screw at the base of each post. The aluminum is light weight and I live in the windy city,so Im going to fill the post with play sand to reduce movement.  The top canopy can be a little tricky to install, the could have made it longer also. Make sure you lay all parts out on a tarp so they will not get damaged or dented up.  You will need to provide your on concrete anchors and screws if needed. Rub all parts down with car wax before assembling to prevent rust later. I love this item, but be real rested when doing.
