I was kind of skeptical to purchase this grille but ended up pulling the trigger on it , installation was not that hard, the hardest part is to swap the camera attachment to the non camera one , after that everything was a breeze, looks great and the material quality is no different from oem, will do another review after couple of months to give more info on the durability and paint fading ( if there’s any, hope not)
