Hooks are much more sturdy than the wood they are connected to. In the picture it shows a single hat on a hook. I would not put anymore weight than that on it! Thin wood panel nailed together in spots with a single finishing nail.
Buy it for the hardware, then throw the rest away. The hooks are probably 50 times stronger than the wood it is mounted to....not impressed with wayfair again. Every few years I try and see if their quality has improved. it has not.
I gave 2 stars and not 1 because the hardware can be use  for actually holding up something if mounted on a different board.
