Gorgeous Unit. Good quality materials. Well made, all the markers for screws etc all lined up and fitted etc. Quite a bit involved in the assembly, but that is expected if you want a decent unit. I put this together by myself, a little difficult in lining pieces up and holding in place and then screwing together. need an extra hand really. But it is possible.
Only problems were at the very end with the finishing touches. (1) Door Hinges with screws were difficult to screw on.Very tight and need a lot of 'force'; (2) The white plastic covers to cover the holes, screws etc, don't fit any of their locations easily; (3) Labels on each piece should be made of nylon or with easily removable glue, they are stuck tight and ripped leaving part of the label/glue residue so now have to scrape and clean. 
But those problems are fixable and just more of a nuisance/annoyance. 
It looks really nice and is a good quality piece.
