After my Roccat Kone has first generation virtually grew genes the spirit thanks to the infamous double-fault, had to be something new. Against Roccat said the fact that it has the manufacturer still not managed after many years, to produce mice with a flawless wheel for me. Still we read reviews that the mouse wheel would break down after a short time. This experience I had to make in my Kone, but this was then exchanged easily and since then perfectly work done their service.
When Gladius I expected thanks to the high quality built-in hardware have no problems so quickly. The technology behind the wheel comes from specialists ALPS, the exchangeable OMRON switch should make the double-fault obsolete and the removable cable ensures that even cable break should not be an issue.
Compared to Kone ergonomics is slightly different. At first I missed the thumb rest, but that's purely a matter of habit. Otherwise, I have nothing to complain about. The mouse is easily detected when you first connect, the lift-off distance is in spite of the optical sensor better than the old Kone, the mouse wheel is rasterized defined and the additional buttons are easier for me to reach than with the Kone. All in all, the mouse for all kinds of games as well as for everyday office use ideal and I can recommend them in good conscience.
