I saw that a number of people mentioned that some of the holes for the dowels did not line up and that was true on the piece I received as well.  That made things a little frustrating.  In some places I bored out new holes, in other places I just left out the dowels.  It should not get super heavy use so I think it will be fine.  
I was impressed with customer service.  The assembly instructions were not included.  I called customer service and they were able to email me the instructions immediately.  That was nice!  It is a very nice cart.
