Positives: Solid construction, the metal frame is well constructed and coated.  Assemble was straightforward, MDF Boards appear solid and strong.  Looks like it will work for a long time.

Negatives: The middle feet attach on a long threaded bolt that goes through the crossbar to the vertical piece above it however, they do not align in a straight line hence the middle feet are slightly wonky.  After assembly and screwing all the shelves in place, I discovered a mark on one shelf (the top one that is most visible).  Having screwed the shelf to the lugs underneath I couldn't just flip the shelf over to hide so will swap with the bottom shelf and place the mark at the back but these two issues do detract from what would have been a 5/5 score otherwise.
