This product is a TOTAL waste of money. The material feels incredibly cheap and doesnt serve any real purpose. The only pro is that it's small enough to toss in your glove compartment .The con is that it's an unnecessary accessory that detracts from the value of your car. I wouldn't recommend this product to anyone..
Pros
Stylish and trendy addition to any keychain collection.
Cons
May scratch easily due to the black coloring and material.
As a result of using this product, I found that it was not only flimsy and cheaply made, but it also did not add any aesthetic value to my car. The black coating easily chipped off and the keychain broke after only a few weeks of use..
For the price, that's a good deal. The keychain got scratched after a while, maybe due to the fact that the glossy finish wasn't applied, but that's incomprehensible to me. Although the valve stems work damn well.
