We've played 7 games with it. The box itself is doing okay, but the the dice channel is already starting to show some wear from fingernails trying to pull it out. It is also easy to push the dice channel too far in and bend the box.
Though I haven't played yet (curse classes!), I was concerned that the tray was too difficult to pull out, so I've stashed a couple toothpicks in the game box. The pull tab sort of folds over in a loop and a toothpick fits perfectly through there and makes it much much easier to pull out
