Review on Circuit Performance VC3 Series Silver Aluminum Valve Stem Caps (Set Of 4) by David Butterfield

I lost one of the plastic caps on the tire when checking the pressure. I was about to buy the plastic when I saw this one. Thinking they would be stronger I bought them. Nice, but three of the four were stuck to the valve stem and I couldn't remove them with pliers. I had to replace the stems. Now I'm concentrating on plastic.
