This product is worse than useless. It is so badly designed that it'll take a ton of time to install and at the end it will not be able to hold up anything of moderate weight. It is such a bad product that I haven't bought anything from wayfair since this purchase. Image the shelf sitting on a pair of plastic crates. The whole thing is supposed to rest on a flimsy metal strip only 3 hooks are provided to hold it up. After this experience if I got this item for free, I would not bother installing/using it. Says it has "cable management" but all they mean by that is there are two cut outs in the back but routing cables is not feasible.
