Very sturdy unit, looks good. Was easy to put together, need two people for some steps due to length and weight of shelves. We didn't follow directions exactly, rather built the unit upside down. Easiest to screw boards to metal frame one by one and then attach them to side pieces. Be sure metal frame is flush with front and back of the two shelves, and there is an equal amount of overhang at each end (~3/4"). There were some predrilled holes that didn't line up, but it was easy to just use the screw to start a new hole.
