Like another review, one of the valve bases had bubbles but this didn't bother me that much as it is cosmetic and covered by the tire. However, one of the valve cores would not unthread properly. After removing it with pliers, I tried installing a fresh valve core, which wouldn't thread in. The problem was poor machining of the valve stem threads.

There were air bubbles in the coating on the bottom when I received.

Work as advertised, good looking and stout. You can feel some resistance when inflating with high volume hand pump so inflating is somewhat slower. Other than that the stems work fine and look good.

I've used both Stans and DT Swiss on my Sun Ringle and DT Swiss wheels. These are super well made and I'd take these over any other company in terms of quality, ingenuity, and value. They seal up cleanly, have two different adapters (round like Stans and rectangle like DT Swiss - I always recommend round) and are now my go-to for tubeless setups with either DT Swiss Rim Tape or Muc-Off Tape, and Orange Seal Endurance sealant.
