Review on Senzeal 5X Long Spike Valve Caps: Aluminum Car Tire Valve Stem Caps with Colorful Bike Tire Caps by Anthony Heinrichs

I would add a photo but the iPhone camera doesn't capture change. I haven't had any problems with deflation like others have said. So when I washed the wheels I noticed that the color changed from black to bronze in daylight. One side of my truck gets the most sunlight. There's nothing on the other side, so when I noticed changes on the bright side, I checked the dark side. The shaded side was clearly black so I replaced it. After a week, both sides took on a bronze tone. Pulled them both out to compare around the house. Same results. It's not that bad, but now I'm looking at anodized valve caps.
