Skateboard Rack with Shelf - Bamboo

I 9rdered two of these for my kids. One was broken on arrival. The glue on the bottom bracket that holds the trucks and wheels wasn't holding properly, and the three pins (very small guage) holding it to the backboard were pulling out. As soon as I hung a board off it, the bottom wood bracket came off completely. I've wood glued it back together and clamped it, but really disappointed in the build quality. I hope this holds, but I'm expecting to have to come up with a more structural solution.
