The bookshelf is very nice. It looks modern and sleek. I had to fasten it to the wall since it is so shallow, there is risk of tipping over. Also, when assembled, there is a risk of it not being 100 perfectly symmetrical around its center. It was tiny bit careening to its side, and since my floor is also imperfect, I had to put a bit of support on one side of it (under two legs) to make it look balanced. Otherwise it looks great. 

Only disappointment was that the metal bolts are visible on every shelf. I had to buy small white sticker dots to cover all the bolts. 

Assembly is not bad. I bought two of these because I needed a certain height to match the dresser next to it, so I used a piece from the second bookcase to attach to the top of this one, which worked very well.
