I got this set with the proslat wall. The wall was installed and I was ready to hang the hooks to finish my job. When I opened the box with the hooks set they had no any packaging. The hooks were in bulk. Most of the plates were scratched and not appealing. One small hook was missing (I had only 11). One small hook was defected. You should see the photo I took, the hook soldered to the hanging plate from opposite side of the plate. Don't tell me this was shipping issue ;) One nut from the large hook was missing as well, so this large hook doesn't stay on the wall. Overall it looks like it was some kind of return from someone else, but definitely too far from new product. As I mention I already put together the wall and obviously cannot return it. The hooks set was the part of this order as one item and cannot be returned separately. Now I am trying to work with Costco customer support (this is where I ordered the set) to resolve the issues with the set, will see how it goes.
One small tip: if you are buying the hooks, buy them separately (or at least check them before hanging the wall), so you have ability to return them, if you'll get the same surprise like me.
