I was totally disappointed in this product. First off, the instructions were very vague and limited. Secondly, the product itself was made with poor quality metal that easily scratches and bends. It was very, very difficult to place the plastic bumpers between each metal rod. What about people with disabilities who would have wanted to install this shelf in their kitchen? It was sold with the premise of being simple and easy to install, but why should I have to use a mallet or hammer to secure the pieces together? For the price of this item, I would not have paid this much money.
