  1. Impressed out of the box 4 Star Review

    Was impressed as soon as I unpacked it, everything felt solid and durable. All parts included (you would be surprised how often that doesn't happen with some stores). Installed easily. Can't vouch for its durability as part of a jack shaft setup yet, but that will come in its own time.
