Great Pergola. Pretty solid. putting it together wasn't difficult. The provided paper instructions in my opinion was confusing but the app was excellent on instruction guidance.  The slotted joist pre-drilled screw holes did not match the other predrilled holes to mount on. Some wood pieces were little warped but that's expected of wood. Overall I would recommend this Pergola. Would be nice to know what the finished sealer is so I can do some touch ups.
