The shelf looks really good on the wall but they need to provide better wall anchors.  The ones they provided pull right out of the wall.  Here's a tip.  Don't try to build all the shelves together and then put them on the wall.  Build each shelf individually.  Then mount the bottom shelf first.  Once that's on, take the middle shelf and put the wall marker thingies on it, rest it on top of the bottom shelf already on the wall and line it up where it should go (level with a level) and then push it to the wall to get the markers on the wall, then mount as you did the bottom one and then attach it to the bottom shelf.  Do the top level the same way.
