Purchased in February 2012, I allows me to make a return on this product. As reported in other reviews, the product rust. Too much and too fast for a product to be in a shower. After a few months, small rust spot appeared, after 3 years the result is not pretty. Regarding the fasteners, when the system is very interesting. Having two shelves, I have 4 mounting points. After 3 years one begins to take off. So I hesitate to take a mounting kit to 10, or a new shelf 20, or just replace it with another mark. Because unfortunately this rust problem is simply unacceptable for this type of material. I put two stars, one for design and one for the fastening system. However, I emphasize the disappointment of quality.
