ASUS is a Taiwan-based computer hardware and electronics company founded in 1989. The ROG Pugio II is the successor of the Pugio, which doesn't have that many similarities with the Pugio II bar the name. The Pugio II is a differently shaped but still fully ambidextrous (symmetrical) mouse, which means it has side buttons on both sides, and although it can be used as a regular wired mouse, it's mainly built for wireless operation, either in the low-latency 2.4 GHz mode or high-endurance Bluetooth mode. The sensor is the PAW3335, PixArt's latest model specifically intended for wireless applications and capable of up to 16,000 CPI at low power consumption, which keeps battery life high. Speaking of which, ASUS cites up to 69 hours of battery life without illumination in 2.4 GHz mode and more than 100 hours in Bluetooth mode. Much like many other ASUS mice, the Pugio II comes with the option to install new main switches without soldering them in (hot-swap switches), which extends the lifespan of the mouse. The side buttons are magnetic and can be swapped individually depending on one's preferences. Another feature is the ability to adjust CPI on the fly with the scroll wheel. Lastly, extensively configurable RGB lighting and full software customization are on board too.
