This was a real beast to put together. The provided screws stripped when we tried to use them, partly because the pre-drilled holes didn’t line up well, and partly because the screws were made of very soft metal. Fortunately, we had better screws to substitute. Once the box was assembled, we discovered the hydraulic lifts do not work. They seem to be jammed, with no way to release them. All in all, the box seems sturdy, but we’re not at all impressed with the overall quality of the parts .
