As former. Gamers and CAD users I was looking for an adequate replacement for my old MX518. I am very satisfied with the mouse, especially for such a low price! After a short settling time, I'm working with it just as much and as well with my old MX518, if not better. The shape is somewhat different (especially felt on the ring finger) but it is smoother. After a few months at home with the Drakonia I even ordered an office for me now. Both gamble and drawing goes excellent with her. Strong buy recommendation from me!
Update: The middle mouse button (the wheel) is relatively stiff. I find that while gambling good (grenades), but while drawing (AutoCAD) is a hindrance (Pan). That's why I prefer the otherwise impeccable mouse from an asterisk. For gaming and for normal office applications, however, I can still recommend the mouse, only partly for CAD applications.
