This is a great looking bookcase we really like it. Set up was mostly straightforward as long as you think it through a bit. When attaching the second side piece you have to make sure the back support screws are in place before screwing the shelves into the side piece. 

Pros: love the look. Very sleek and the ovals are a very interesting design. Bonus: my cat likes to walk through the oval parts!

Cons:
 1) The finish had areas where the quality wasn't where I would expect on a new piece of furniture. The top piece wasn't completely smooth and I could see some faint white dots. A couple small areas also looks like it had been scraped off a bit. 
2) the top piece didn't sit flush against the frame and I don't know if I just wasn't careful enough or if it's a design flaw. I would just be extra careful with two two small long pieces at the top to make sure the top can sit properly.
