While the overall quality of this item is decent, the back is two pieces (not the usual solid piece) and no matter how hard you try, there is a small gap between the pieces in the middle.  I had purchased two so I would have matching bookcases and both ended up this way.  While I'm not an expert handy-person, I have put enough of these together to know what I'm doing.  I'm going to tape the back so light doesn't come through because it bugs me. I would not buy these bookshelves again.
