ASUS ROG Keris II Ace Review
Bottom Line
Choose the Keris II Ace for a light, fast right-handed FPS mouse with top sensor and wireless performance. Skip it if you need cheaper value, left-handed support, grippier coating, or simple software.
Best for
Best for right-handed competitive FPS players who want a very light ergonomic mouse with strong 2.4GHz wireless, high polling-rate support, smooth glide, and a top-tier sensor. It also suits users who value Bluetooth and onboard controls as secondary conveniences.
Not for
Not ideal for left-handed users, budget buyers, players who hate Armoury Crate, or anyone who needs a naturally grippy coating without tape. MMO/MOBA players who want many side buttons should also look elsewhere.
Verdict
Reviewers describe the ASUS ROG Keris II Ace as a high-end esports mouse built around speed, low weight, strong wireless performance, and a highly capable sensor. The strongest praise goes to FPS tracking, glide, low-latency 2.4GHz use, and a shape that many right-handed users found comfortable. The tradeoff is that the same weight-focused design leaves some reviewers unimpressed by the coating, side-button sizing, scroll feel, and Armoury Crate experience. Battery life is generally good, but high polling rates reduce runtime, and the booster/dongle setup can feel clunky. Overall sentiment is positive, especially for competitive players, but value depends heavily on whether the buyer actually benefits from premium polling, sensor, and weight specs.
