The concept of this sandbox is great but the quality of it is terrible.  I would recommend buying materials and building on your own.  As other reviewers said, screws/hardware are poor quality.  The wood did not hold up very well. Within a year of owning it is pretty beat up and rough looking.  We live in a part of CA that doesn't get snow, and our weather is very mild, so I expected this outdoor structure to last much longer than it has. I would not recommend.
