Nice unit with some issues.  First, I love these shelves. They look great in my family room. However,  we had repeated issues with the shelves with the drawers.  All of the cabinet units were fine.  The drawer units, however, were all damaged.  Wayfair did send us replacements, but the replacements were also damaged.  So, we used the good parts from the different boxes to make one drawers unit.  I think the issue lies with the way these are packaged.  The cabinet units are very snugly packed...no moving around.   The drawer unit packaging was not as secure.  Every drawer unit box had parts moving around freely inside, causing damage.  

So, for the shelves...a 5.  But, because of the poor packaging of the drawer units, a 4.
