Overall, bueno-tastic. Box seams are a little loosey-goosey when loaded and full, and will need reinforced with packing tape for true rigidity. Also, there is an up/down to the box and it is easy to assemble in the wrong order, but if you ain't as OCD as me, then there's no issue with that anyway. Boxes are perfectly engineered for size and stack 3 rows high on each other very well.
