We purchased three to provide a privacy screen. We had the planters sitting on the edge of a patio however strong winds would tip them over even with the planter containers and a paving stone placed between each pot. We just redid them placing a 5ft metal rod though the trellis and planter leg staking it into the ground and supporting the back lower horizontal support onto additional pavers to allow the front of the boxes to remain on the patio. Time will tell if it solved our problem. Otherwise  the planters look good and the trellises provide good privacy.
