The Sojag canopy parts are well constructed. Very nice finishes on every piece. It would be pretty hard to complete this project without a helper. The assembly can be done in one full day. Became quicker construction when the impact gun was used, however we are used to that tool and knew how to not over tighten. We used a square early on to keep the upright supports square. It should be emphasized in the directions when to final tighten screws. The cross supports which secure the roofing material should NOT be tightened until all screws are installed from above which hold the roofing material down. This helps to line up the bolts through the tubing/cross supports. Packaging was good. Instructions were concise. Labeling on the parts was good.
