Just did the install. nice system
it took my wife and I about 4.5 hours to fully install this round top. The footprint is actually 13' x 20'. the unit seems pretty sturdy. You definitely want to erect this on a low wind day. and get some extra anchoring system. But so far we are happy with the structure and it feels very solid. The design is smart and the tension system of the canopy is pretty slick. Make sure everything is square and think ahead. The instructions or not the quickest way to erect this structure, but they may have them that way for liability reasons. We erected the top half first then moved it to position, then added one side of the legs and lifted the frame up to slide the other legs in and anchored it down. Then we added the canopy ends then top and installed the lowers and bolted them together. we also laid a tarp down on the floor on the inside to reduce some of the ground sweat moisture building up. we'll see....but other than needed to drill out a few of the pre-drilled holes, it's a pretty easy system.
