ASUS ROG Keris II Ace Wireless Gaming Mouse - 54g Ergo Precision

Our review of the ROG Keris II Ace finds it aimed at serious FPS players and long-session gamers who want a featherweight, precision mouse with flexible connectivity. The single biggest reason to buy is the combination of a pro-tested 54g ultralight ergonomic shell and an industry-leading 42K DPI sensor, which together deliver fast, accurate aim and comfortable control in marathon play. Its long battery life and tri-mode options mean it works equally well as a wireless primary or a travel companion for multi-platform setups.

Key Features

• Pro-Tested 54g Ultralight: The low weight reduces hand fatigue and allows faster flicks and smoother tracking during long FPS sessions.
• ROG AimPoint Pro 42K Sensor: Very high DPI with <1% CPI deviation and track-on-glass capability provides consistent precision on most surfaces.
• Tri-Mode Connectivity: Switch between low-latency 2.4 GHz RF, Bluetooth, or USB-C wired mode for flexible use across PC and Mac.
• ROG Optical Micro Switches: Reliable, instant actuation rated to 100 million clicks to avoid double-click issues in competitive play.
• Premium Components: Includes a ROG Paracord, 100% PTFE feet for smooth glides, and onboard controls for DPI, polling rate, and lighting.
• Sustainable Packaging: Packaging uses less than 1% plastic by weight, reflecting a reduced environmental footprint.

Who It's For

The Keris II Ace suits FPS players and esports enthusiasts who prioritize speed, low weight, and pinpoint tracking; co-development with pro players makes it a focused choice for competitive play. Users who value long battery life and the option to toggle between wireless modes will also appreciate the convenience of tri-mode connectivity and the ROG Polling Rate Booster for fast wireless response.

Casual users who prefer heavier mice, large-palmed claw-hold players seeking extra heft, or shoppers on a tight budget might look elsewhere; the Keris II Ace targets performance and ergonomics over being an entry-level value option.
