My GB came split as well when i opened the box.. (i got a replacement) But I noticed the box corners weren't actually glued together properly. Whoever did the routing to join the corners really screwed up. If you looked at the top of the corners you could see a gap running down the box, wood corners aren't touching completely. Therefore there was no solid bond. Whoever is creating the boxes is shaving too much wood off. It's not the material used, someone is measuring wrong.
