I needed a shoe rack which would fit on a wall in a space smaller than the width of this rack. I could not find such a thing. I bought this rack and cut each rod down to size before assembling it. It has been working like a charm. I am so glad it can also be attached to a wall.

Pros: Can be modified in width, can hang on wall.
Cons: Wish side plastic a little thicker, but so far it has held up.
