The instructions should have made it clear you were going to need to shears capable of cutting chicken wire and that chicken wire was not pre-cut.  The instructions failed to note that the holes in poles needed to be towards the corners and/or pointed towards the ground for corner bracing to be attached.  I would also suggest putting chicken wire on the door before you install it to the frame and add hardware.  The 3 star rating is tied strongly to the instructions versus the product itself.
