So far they have been great. They are durable, lightweight, and look awesome. Their customer service is also good, very responsive.
What can I say, they're valve stem caps... They fit great and look fire. Package is super nice which makes it feel more premium. Caps are laser engraved with logo on top. A nice subtle detail to add to my build. Would 100% recommend to anyone looking.
Bought the blue set and they match my dark blue wrx nicely. the caps are short which leaves the base of my valve stem exposed but since the caps are heat treated, the transition from the blue tip to the brownish base match the exposed valve stem. Very happy with my purchase
