This pergola was received promptly within 3 days and was exactly as described.  We had our brother and son put ir together for us.  It took them about 4 hours (that may have included a lot of talking).  They said it was fairly easy as long as you took each part out of the box and grouped them together.  There were a lot of parts.  They drilled it into the concrete slab, but had to rent a special drill to do so.  It looks very nice on our patio over our backyard furniture and provides just the right amount of shade.  The back pull down shades do blow in the wind if it get get windy, so they do need to be rolled up if there are windy conditions.  The top canopy has holes along the sides which helps divert the wind so that doesn’t need to be pulled back as frequently.  All in all. I give this a 5 star pergola and would recommend it.
