The box was easy to assemble (it took about 90 minutes to do myself) and is fairly sturdy. However, the plastic sides bow out, causing a gap between the lid and box sides. A fair amount of water got into it during the first rainstorm, which is very disappointing. While it'll provide a decent cover for items from sunlight and pollution/pollen, I'll have to bring all of the contents in during storms. Overall disappointed in the quality.
