Of all the ready to assemble, particle board furniture I have bought and assembled, this sideboard is one of the best quality.  The holes were drilled accurately, the instructions were clear and correct, and everything fit together nicely.  I would rate it 4.55.  My only minor complaints are that (1) one of my drawer sides was missing three small holes for the drawer slide and (2) the holes for the dowels were slightly too large, resulting in a loose fit.  However, these issues are not enough to prevent me from recommending it to others.
