I found assembly to be relatively quick and easy.  I was able to put together the bookcase alone in less than an hour.  I think it looks nicer than other comparably priced options.  I had no problem getting the brace bars attached to the back but even with both on, I feel that it is not outrageously sturdy - but it is strong enough to hold a fair amount of books.  Overall, for what I paid, I am happy with it.
Also ymmv but I was shocked at the fast delivery.  I live in a very rural area and this was delivered to my door in two days.
