Purchase your own washers, lock washers, bolts, and nuts. The nylon ones provided are junk and cross thread when loosing them to adjust the canopy position when mounting. I used Gobi ARB mounts so I can’t speak for the ones provided. Bag and zippers appear strong. Canopy should have been double stitched and multi layered in some spots, especially where the Velcro is. Legs lock by turning and appear to be flimsy. I do not see this as a multi year lasting product. I think I will return and seek out others of better build quality. For a season of camping, it’s probably a great purchase.
