After our purchase a month ago we thought this box was extremely durable beyond what we first thought. But to be dissatisfied shortly after with the lid. After each rain the lid is showing a dip in the middle and top is already fading showing every dimple from the inside pattern. I’d give this box a 4 or 5 star but the lid was the deal breaker. I’d rather not return to Cosco because how had it was to put together. Wish Lifetime would replace lid with better design and remedy a perfectly good box.
