The optics of the shifter knob was not bad, but the possibility of attaching was not great. I had first tried it with the original sleeve, but it was much too thick for the lower end ring. So I had to buy a new thinner cuff. The is also not remained below the lower end ring and slipped out again. I had no longer edit the connection ring machine and then of course the stop was not as good and the optics. Despite the appearance, I would not buy it.
