My review is mixed.  Although i love the Pergola, the experience of assembling it and ultimately realizing that, although the box indicated 12X10, the actual size is more like 10X10.  we were very careful with the measurements when we purchased it and you do not realize until after you assemble the frame and connect the cross bars that true dimensions.  

The directions are very poor.  You don't learn about a important feature or step that impacts another step at the right time.  we had to disassemble parts 3 times to ensure a later step could be completed.  Assembling this unit took 5 hours by someone that works with industrial mechanics daily.  We were not going to take apart the many pieces to return when we finally discovered the unit was 2 feet smaller than indicated.  This would be a 5 of 5 rating if the right size was shipped and the instructions were more thorough.
