The Asus ROG Keris II Ace delivers a compelling combination of high-end features and performance rarely found in a single FPS gaming mouse. With its powerful sensor, blazing-fast polling rate, dual wireless connectivity, and ultra-lightweight design, this mouse offers a significant advantage in competitive gaming. Let’s delve deeper into what makes this mouse a top contender.
Design and Build: Lightweight and Ergonomic
The ROG Keris II Ace prioritizes speed and maneuverability with its featherlight 1.9-ounce (54-gram) design. While the nylon back feels similar to plastic, it contributes to the mouse’s overall lightness. The symmetrical shape conforms comfortably to the hand, providing optimal control. Six programmable buttons offer ample customization options, while the premium PBT material used for the main clicks ensures durability and a satisfying click feel. ROG Optical Micro Switches provide a rapid actuation speed and are rated for an impressive 100 million clicks.

Connectivity: Wired and Wireless Excellence
The Keris II Ace excels in connectivity, offering both 2.4GHz Wi-Fi and Bluetooth options. For wired use, a flexible 6.5-foot (2-meter) paracord is included. Bluetooth mode allows pairing with up to three devices simultaneously, making it seamless to switch between a gaming PC, laptop, and even a handheld console. The included Wi-Fi dongle, when used with the polling-rate booster dongle, enables a blistering 4,000Hz wireless polling rate, currently the fastest available for wireless devices. Wired mode supports up to 8KHz polling rate, comparable to top-tier competitors.
Gaming Performance: Precision and Speed
The ROG Keris II Ace boasts a remarkable 42,000 DPI ROG Aimpoint Pro Optical Sensor, providing exceptional precision and responsiveness. With a maximum speed of 750 inches per second and 50g acceleration, this mouse handles even the most demanding maneuvers with ease. In games like Call of Duty: Modern Warfare 2 and CounterStrike 2, the Keris II Ace performs flawlessly, delivering smooth tracking and lightning-fast actuation. The 100% PTFE feet ensure effortless gliding on various surfaces, including glass. The comfortable grip and strategically placed side ledge enhance control and reduce hand fatigue during extended gaming sessions.

Battery Life and Software: Customizable and Efficient
Battery life in Wi-Fi mode with default RGB lighting is approximately 66 hours, while Bluetooth mode extends this to nearly 90 hours. The Asus Armoury Crate app provides comprehensive customization options, allowing users to adjust DPI, assign commands, create profiles, and tweak settings like liftoff distance and polling rate. While the Keris II Ace has only one RGB zone (the mouse wheel), it can be synchronized with other Aura Sync compatible devices for a cohesive lighting setup.
Final Verdict: A Premium Esports Mouse Worth Considering
The Asus ROG Keris II Ace comes at a premium price of $159. However, its unique blend of features, including a 4,000Hz wireless polling rate, dual wireless connectivity, on-glass tracking, and an ultra-lightweight design, justifies the investment for serious esports enthusiasts. If you’re seeking a top-tier gaming mouse that delivers exceptional performance and a competitive edge, the ROG Keris II Ace is a compelling choice.
