Extremely versatile and just what I needed for a narrow space.  It was easy to put together and feels quite robust though I wouldn't recommend storing heavy items on it as it's not secured to the wall.  It is perfect for a few books and odds & ends in the hallway.  I have slipped a few pieces of rug grip under each leg just to stop it from shifting against the wall and scuffing the paint in case anyone knocks into it, I don't think you'd need any on a carpeted floor but on wood it's a simple solution to keep it in place.
