The espresso color is more reddish brown.  The quality is good.  There were just a few small areas that didn't get the stain completely, luckily it wasn't in a noticeable place.  The tricky part was how far out the screws should be from the wall so they would slide into the grooves properly.  We did end up putting small round adhesive protectors to the back of each shelf close to the bottom.  That helped to level each shelf.  All in all their classy and I love the floating look.
