It went together fairly easily & quickly, although it takes a bit of space.  I love that it is 86" high.  It is difficult to find bookcases that are both tall & wide.  It looks great with our high ceilings & balances out the room perfectly.
The only real con is that the top is not finished, so I stacked the styrofoam packing on top to fill the spaces in order to place something on the top of the bookcase.  I'm hoping our tall friends don't notice.
The 2nd shelf from the bottom hits right where our plugs are, too.  It would be nice if the shelf was a couple of inches higher, but it's not a deal breaker.  I will probably look for a power strip with a flat plug.
