Two of the twenty-three wheel nuts were not tightened properly. They wobble because the hole or thread wasn't cut properly. They work, but I just keep an eye on them. I guess their QC didn't get it. Nice packaging and design. I would give the product 5 stars if the workmanship was good. First, I screwed all the tabs by hand so they didn't cross over. They were used on brand new rivets so I know you didn't have the same thread before threading.
