Canopy slides and is constantly coming loose. Canopy bars break free from side grommets/attachment bracket and then poles fall out leaving the entire Canopy hanging.  This after 2 weeks of use with no bad weather, basically leaving it unusable unless you want to constantly fix poles.  Also pole attachment hardware is plastic so im sure with the constant putting it back together these will wear and break. Waste of money compared to other pergolas of the same price.
