The unit is well made, and we were able to assemble it with no problem, except for one thing.  The instructions say not to tighten the screws, but it is difficult to put together the upper unit unless you insert the screws. When I discovered that the top shelf was backwards (creating a lip over the cubicles) I could not remove the screws. The unit is still usable, but you should include a little diagram of the assembly process for the upper unit so this does not happen. 
The other issue was that the box on one corner was damaged, and so I did not want to send the package but, but we have one corner that looks pretty beat up.  I should have sent the whole thing back, but did not.  The packing seemed to be okay, but not on one corner.
