These shelves are just as described- pretty straightforward.  They have a nice, clean look and should be easy to install in most circumstances.  My house is old and has plaster walls and who-knows-what going on underneath, so we did have some trouble getting all of the anchors in.  We were only able to get 4 anchors in one of the shelves.  It seems sturdy enough, but I won't test the full weight on it.  The other shelf has all 6 anchors, and I was able to put books on it.
