Still unboxed, but bought to use as a room divider without shutting off the two areas totally. Variable set up with the shelf dividers gives more space options.
Looks like it has everything I required it for. 
Job done. 
A few days after my initial review, I have now assembled the bookcase. All was good except on three of the shelves. I found the screw and dowel holes were not locating correctly, so had to cut a dowel level on one end of each of the shelves, as I had already glued it in place and also had to drill new pilot holes for the screws.
Apart from this issue it looks good and does the job it was bought for.
