At first my husband was apprehensive, but after seeing the quality of this product he quickly changed his mind.  This is awesome and we love it.  We live in Wyoming, so we do have wind, so we are careful to make sure the louvers are open when we are not around to avoid the possibility of it becoming airborne.  It is definitely a 2 person assembly job, but my husband and I were able to assemble with no problems.  Came packaged in 5, well labeled boxes.  No missing or damaged pieces. Directions were just diagrams, it would have been nice to have a little explanation, but it all worked out. Pictures show the louvers open and closed.
