This box is quite sturdy.  It is recommended that two people work on the assembly but I did it myself.  It took about 2 hours and keep your tools handy.  A couple of times I had to drill some starter holes since the self-tapping screws were not catching.  The hardest part is assembling the base to the four sides.  A rubber mallet is very helpful.  The seam on the base where it connects to the four sides is about 1 inch off the ground and it really did not look 'water tight' so I laid a bead of caulking all around the base where it connects to the four sides, which I am sure will do the trick.  Overall, I would say this is good value for money,  not that hard to assemble, and should last a long time.  Also very nice that it is lockable.
