This product is misrepresented by Wayfair.  The pictures, installation guides, and online information does not mention how thin the steel is, and the entire structure is so weak that it would be dangerous considering how Wayfair the level of weight this product can hold.  The top and bottom shelves are held together by a 1/4" piece of plastic, which can snap and entire shelve can collapse.  Considering how dangerous this product would be for cars, and any person in the garage when it collapses.  On top of all that Wayfair insisted that I pay $83 dollars for shipping to return the product.  I'm done with Wayfair, and I encourage all to stop shopping at Wayfair.  Bad Product, Bad customer service, and overall they just don't care.
