Trellis arrived in perfect shape in two undamaged boxes, with all parts present and accounted for.  Instructions are easy to follow with clear pictures to guide you through assembly.  It will help to have a post digger tool, even better a volunteer to dig the holes.  I added some drainage rock to the bottom and eyeballed the holes trying to level the site before placing the unit into the holes.  If you are way off level you will be lifting the unit, and the additional weight of the attached 4X4s in and out of the holes more than once.  The drainage rock makes leveling easier.  It is beautiful, a high quality vinyl, and worth every penny.  I wound up opening a Wayfair credit card for $40 off, also noted that it is more expensive on other sites.  Very pleased.
