Looks and feels great, slight fitment issue in my case.
For some reason, the one thread adapter I needed didn't fit right while the other 3 were just fine. Threads look identical, but had to basically force it in, shaving some aluminum off as I went. Only other thing, which is by nature of the design, is that since it's a ball, it doesn't cover below at all and the reverse lockout sleeve is visible.
Feels and looks great though.
Had an issue with the m12x1.25 thread adapter not screwing all the way into the ball. All the other adapters seemed to work. Not a deal breaker though. Good price for a nice solid piece.
