I needed a long, narrow shelving unit to store books and other items for my bedroom.  I bought the black model and put it on it's side.  I wanted something that wouldn't take up all of the wall space.  This unit was perfect.  It took a bit of time to put together and you'll need a good-size space because there are lots of pieces.  The directions are easy to follow and I didn't need help from my husband (except to move it in place).  My only complaint is that the stickers you get to cover the bolt holes fall off.  Once the shelf is filled with books, etc. you can't see the holes inside the compartments, but they are visible on he sides.  Great for my purpose!
