I bought 2 of these to store my outdoor holiday decorations. They seem sturdy and have stood up to 2 recent storms we had with 50mph winds. They have not shown any signs of leaks. I put them together with my teenage son. The 2nd one went faster since we knew how to pre assemble some of the pieces. I created a base to set them on because that side of my yard tends to puddle and I plan to raise the soil level and put down stone in the spring.
