That still does not define enough engaging wheel and the Claw-Grip for players not optimally positioned thumb buttons are the only criticisms that the G502 Core Proteus must be of Logitech in my opinion is like. The equipment is very good, the weight system helpful and the software falls Logitech typical of very extensive and is easy to use. In addition, it includes features such as underground calibration or the switch-off function for the Angle Snapping which again enhance the anyway very good performance of the unprecedented 12,000-dpi sensor a bit. With the equipment and the properties, respectively the ergonomics and the keypress points the Logitech G502 Proteus Core pulls definitely past my Roccat Kone XTD favored so far, the current price of 69 is justified.
