I have owned this size and style box for over ten years.  It is stained, sun faded and has the black top versus the gray, but no cracks or plastic failure at all.  I liked it so much I just bought 3 more.  They are built identical to the one I have had forever.  I am very pleased with the durability of this product.  It makes for a perfect grab and go container, as well as just on the floor of the garage storage for camping gear etc.  They are lightweight when empty, and can hold very heavy items if need be.  I have 4 now, all slated as bug out boxes, or supplemental bug in cache.
