As a result of my tests, I determined that these valve stem caps were well-made and brought some flair to my tires. The American flag emblem is a nice touch for those who want to show some national pride. The caps were easy to install and stayed securely in place. The only downside is that the price is a bit higher than generic valve stem caps, but you're paying for the design. All in all, a great addition for those who want to add some personality to their car.
