I believe that's the one I'm using. It's pretty great. That said, unless something changed, remember to update the firmware so that you can use the internal memory allowing you to use custom DPI without any problems. It was a while ago, so I don't remember what problem I had with the settings, but using the latest FW fixed it.
Also, instead of using G-Shift for the rightmost button, which was sometimes problematic for me in XIV, I recommend setting Shift/Alt/whatever button there. Just set up your shortcuts accordingly, without using the G-shift mode. Maybe they fixed it already, haven't checked.
Edit:
While this post makes it sound like the mouse isn't good, aside from the above problems which can be solved in a few minutes, I've been using it for a few months without any hiccups.
