Not only does the ROG Gladius look an awful lot like the Razer DeathAdder, it’s very nearly the same size. To compare, the Gladius is 4.96(L) x 2.64(W) x 1.77(H) in / 126x67x45 mm and the DeathAdder is 5(L) x 2.76(W) x 1.73(H) in / 127x70x44 mm.
There are three lighting zones on the ROG Gladius – the scroll wheel, the ROG logo towards the end, and the sensitivity indicator near the button in the center on top.
The Gladius comes with two microUSB-to-USB cables as part of the swappable cable system. The cables each have different lengths and are 2 meters for the braided cable and 1 meter for the regular rubber cable.
Much like the Razer DeathAdder, the Gladius has two side thumb buttons and grips on the sides of the mouse.
When viewed along its length, we see that the Gladius does slightly differ in its ergonomic design from the Razer DeathAdder. The curvature skews towards the left instead of being centered.
Looking underneath, we see four large gliding feet. These have to be removed and then replaced if attempting to change or replace the Omron switches inside the mouse. The locking switch holds the detachable USB cable firmly in place. Lastly, the 6400 dpi IR optical sensor can also be seen.
