1. Paid extra for AM delivery and driver shows up at 12:40 2. Without using any hammers, one of the wooden dowels went through the shelve (the hole must have been drilled really close to the surface) 3. The holes of the inner divides of the upper unit are in the wrong place (fine for top shelf but wrong for fixed shelf). No idea yet how I am going to deal with that, but for sure it is going to be extra work 4. Not clear how to attach upper unit to desk. The upper unit assembly instructions refer to "desk fixing assembly," but they say NOTHING about fixing the upper unit. In fact, my desk instructions are for a different desk (one without the side unit)
