0/10.  The construction and materials used in this product are so shoddy.  Multiple screws become totally stripped while we attempted to build this bookcase, and one would not fit in all the way, so it's sticking out by an inch.  The metal braces that are supposed to fit on the back of the bookcase for additional support were sized completely wrong -- 1 out of 4 actually fit into both holes they were supposed to screw in to.  We fit a second on by drilling a new hole into the bookcase.
This bookcase does look nice, but it was 100% not worth the time and effort and frustration to build.  So many of the screws are stripped that we fully expect to burn it when we move, because we will never be able to take it apart.  And we expect to fall apart any day.
