Color is more of a gray than black as pictured. Also they are tight to fit into my slatwall so perhaps not considered cross compatible.

Great for hanging lots of things

Not as useful as I thought they would be.

I have to say I'm very impressed with my entire flow wall system that has now been up in my garage a few weeks. I got a starter kit that had different hook types and bins. After I used all the hooks, I had extra space on the wall and more items that needed hung. I found this 10 hook kit and wasn't really sure what to expect in terms of strength knowing if was relatively cheap compared to the other hooks for sale, which were the same hooks in the starter kit. I have to say I was pleasantly surprised by what I was able to get them to hold. I give this 5 stars for adding extra hooks to my set, holding what I need, and being a great value.
