Predrilled holes for self-tapping screws did not line up which put strain on the bamboo they were going into and cause it to split in several places.  ALSO, the allen wrench supplied was soft and rounded off which meant it just spun rather than screwing in the screws.  ALSO, when using a well-made allen wrench, a couple of the screw heads broke off before they were in far enough to tighten components together.  Will give it one star for the finish on the bamboo....otherwise this is a piece of junk.
