They lookGreat and I like the idea of anti theft. But if you leave the little o ring in them they will cause leak at the stem. At least they did in both my fords with aftermarket rims
Pros
I love it
Cons
The chrome finish may tarnish over time, leading to a less attractive appearance
I was happy to receive this product, I have kids on bikes that like to come by my truck and take my valve stem caps for there bikes so I bought these so they can ride in style lol
