I am giving 5 stars because of the pergola itself but ....this was a monster to put up not because of all the parts but  because of the HORRIBLE INSTRUCTIONS!!!  They need to go thru and completely rewrite. Pictures and instructions don't match ( Written instructions Attach part R to C1 and C2 but the you have to do  first B1 and B2 which the instruction for that piece say nothing about part R and and you don't realize until after you do the next step). To save yourself the headache and time if you can afford the assembly pay for it!!! I tried to go back and purchase the assembly but wasn't able to do so.
