Great bookcase, exactly what a needed for an awkward 35 by 40cm corner..
It isn't the tallest bookshelf in the world, but I wouldn't be able to reach it if it was much higher and plan to stick a good quality fake plant on the top, so it can act as a bit of a plinth.
I'd recommend reading the reviews before you build it though, as my boyfriend kindly offered to put it together for me and I told him about the reviews stating that it's confusing to put together due to the odd layout of the shelves and asked him to read through them. He said that if he hasn't read them, it may have been an issue. But he did it on his own in about an hour I think, and it looks great. 
I would say that perhaps the anthracite colour also helps hide a multitude of sins, as I don't know if another colour would look as solid and decent quality.
