Customers praise this product's sturdiness and wind resistance, with many reporting it withstands strong winds and heavy weather. Assembly is generally considered easy, although some found the instructions unclear or parts difficult to identify. Durability is a mixed aspect; while many report long-lasting use, others experienced tears or damage to the cover, particularly in harsh conditions.
