Overall the fit and finish is good. There was some extra material around the injection gate that had to be cleaned up. The lettering is clean and crisp. The caps feel solid, almost overbuilt.
A detail of the "Wrinkle Black" finish on the Planck Hi-Pro aluminum milled bottom. The unique finish is executed well and feels very durable. After a few weeks of use it appears to resists scratching and flaking well.
