This is third bookcase I've purchased from wayfair (different sizes, same brand). I had issues with two of them. An 84" in espresso that came with cherry shelves and now this 36" that arrived with scratches on two shelves. The first issue was resolved quickly with them sending a new set of shelves. The scratched shelves are being replaced but have not received them as yet. 
These are beautiful bookcases and I have received many compliments. Love the way look, the only thing I would change would be the backing would be a solid piece instead of there being a seam up the center of each shelf.
