We acquired this storage box recently. It was easy to assemble, except that the front and rear panels require a bit of curvature to conform to the base. Thus, the seams have large gaps that will allow insects and water to enter freely. I applied a tension strap around the girth of the box to compress the seams and applied Gorilla tape to the inside to seal the seams. My next step is to caulk the seams from the outside with clear silicone to keep out the bugs and moisture. I thought a Rubbermaid product would have been moulded to fit better. The main reason we bought this box is the available space...all other competitor boxes were too large, but seemingly better quality.
