ASUS ROG Keris II Ace Review
Bottom Line
Choose the Keris II Ace for a 54g ergonomic FPS mouse with excellent sensor performance and 4K wireless polling. Skip it if you need left-handed support, a grippier coating, or a lower price.
Best for
Best for right-handed FPS and esports players who want a very light ergonomic wireless mouse with precise tracking, 4,000Hz wireless polling, Bluetooth for secondary devices, and strong battery life.
Not for
Not for left-handed users, strict fingertip grippers, MMO/MOBA players who need many thumb buttons, or buyers who want a cheaper mouse with a grippier coating and simpler software.
Verdict
The ASUS ROG Keris II Ace earns broad praise for combining a 54g right-handed ergonomic shell, a 42,000 DPI AimPoint Pro sensor, smooth PTFE glide, 4,000Hz wireless polling, and strong battery life in a competitive FPS-focused package. The tradeoff is that its premium spec sheet does not erase every feel issue: reviewers split on the coating, side buttons, scroll wheel, and Armoury Crate experience. It is strongest for players who value light weight, stable 2.4GHz performance, and palm or relaxed claw comfort, while fingertip users, left-handers, and value-focused buyers have clearer reasons to hesitate.

Feature Scorecards
Pros
-
The 42,000 DPI ceiling is repeatedly highlighted as class-leading, though reviewers often note most players will never use the upper range.
-
Weight is a clear strength, with nearly every review emphasizing the 54g or 1.9-ounce design as exceptionally light for an ergonomic wireless mouse.
-
Switch durability is excellent on paper and in reviewer discussion thanks to ROG optical switches rated for 100 million clicks and reduced double-click risk.
-
Measured and reported click latency is very low, with reviewers citing roughly 1ms or sub-millisecond behavior depending on mode.
-
Wireless performance is excellent overall, with stable 4,000Hz operation, no dropouts, and strong sensor performance frequently reported.
-
Polling rate support is one of the main selling points: 4,000Hz wireless and 8,000Hz wired are repeatedly highlighted, but 8,000Hz is not wireless.
-
Sensor performance is a standout strength, with the AimPoint Pro repeatedly described as accurate, high-spec, smooth, and reliable.
-
FPS suitability is excellent, with reviewers repeatedly tying the mouse to esports, Valorant, Counter-Strike, and high-speed competitive aim.
-
Connection stability is a major strength, with reviewers repeatedly reporting no dropouts, no stutters, no hiccups, and stable high-polling wireless use.
-
Wireless latency is treated as excellent over 2.4GHz with high polling, while Bluetooth is repeatedly framed as a convenience mode rather than a competitive mode.
-
Durability evidence centers on optical switches, double-click resistance, consistent performance over time, and serviceability such as hot-swappable switches.
-
Surface compatibility is excellent, with reviewers citing glass tracking, surface calibration, and reliable behavior across mouse pads, tables, and other surfaces.
-
Multi-device support is a meaningful advantage because Bluetooth can pair with several devices and the mouse is described as useful across PC, laptop, console, or travel setups.
-
Tracking is one of the strongest consensus wins: reviewers describe precise, smooth, accurate movement across games and surfaces, though one noted very high DPI becomes impractical.
-
Reviewers consistently find the tri-mode setup useful, with 2.4GHz wireless treated as the main gaming connection and Bluetooth/USB adding flexibility.
-
The right-handed ergonomic design is a core strength, frequently described as comfortable, esports-focused, and well-shaped for palm or relaxed claw use.
-
Button responsiveness is broadly positive, with reviewers calling clicks snappy, low-latency, precise, or consistent, even when switch feel is debated.
-
The sensor's 50g acceleration rating is repeatedly cited as part of its top-tier performance spec, with no practical complaints about acceleration handling.
-
Most reviewers praise the balance as centered and easy to control, but one detailed teardown-style review found a slight forward bias.
-
Glide is consistently praised thanks to smooth PTFE feet, spare feet, and strong performance on cloth, glass, and other surfaces.
-
Shape comfort is broadly positive, especially for small-to-medium ergonomic users, but fit varies by hand size and grip preference.
-
Bluetooth is a well-liked convenience feature, especially for multi-device and non-gaming use, while reviewers still favor 2.4GHz for competitive play.
-
Palm grip comfort is a major strength for small-to-medium or relaxed palm users, though very large hands may prefer bigger ergonomic mice.
-
Ecosystem integration is positive through Aura Sync, Windows Dynamic Lighting mentions, and the ROG Omni Receiver's ability to pair with other ROG peripherals.
-
Programmable button coverage is solid for an FPS mouse, typically five or six physical buttons plus scroll directions through software.
-
Skate durability evidence is limited but positive, with one reviewer reporting the stock skates held up well and no dust or grinding on glass.
-
Build quality is mostly praised as rigid and solid for a 54g mouse, with only a few unit-level notes about creaking, rattle, or average feel.
-
Left/right click quality is generally strong, with PBT or optical construction and consistent feel praised, though a few reviewers criticized travel or hollow feel.
-
The included cable is usually described as flexible, light, or low-drag, though one reviewer found it somewhat stiff and another called it only medium.
-
Long-session comfort is mostly strong due to low weight and ergonomic support, though some hand sizes reported cramps or fit issues.
-
Materials quality is mixed-positive: the nylon/PBT construction supports low weight and rigidity, but coating feel and premium texture divide reviewers.
-
Charging convenience is positive overall thanks to USB-C, an included cable, and a universally sized port, though charging was not a major focus of most reviews.
-
Button remapping and control customization are well supported through Armoury Crate or onboard controls, including DPI, polling, and command assignment.
-
Onboard memory and onboard controls are meaningful positives, with reviewers citing hardware profiles, on-device controls, and software-free settings changes.
-
Portability is helped by Bluetooth, dongle storage, multi-device use, and travel-friendly wireless operation, even if the booster setup can be bulky.
-
Battery life is generally considered strong at normal wireless settings, though several reviewers note high polling rates and RGB reduce runtime.
-
Claw comfort is generally good for relaxed claw users and smaller-to-medium hands, but not every reviewer found the shape ideal for aggressive or large-hand claw use.
-
Macro support exists through Armoury Crate, but it is not a headline strength and onboard macro behavior is more limited.
-
RGB is limited to the scroll wheel but appreciated because many ultralight esports mice omit lighting entirely; some reviewers dislike the execution.
-
Premium feel is mixed: many call the mouse solid or feature-rich, but coating, price, and button feel stop some reviewers from calling it universally premium.
-
Switch feel is mixed-positive: many like the crisp optical clicks, but some find them mushy, hollow, heavier, or less satisfying than mechanical alternatives.
-
Software stability is acceptable in the lighter Armoury Crate Gear experience, but broader Armoury Crate concerns remain around bloat and background processes.
-
Lift-off distance is adjustable but not universally loved; reviewers liked having the control, while some found the low/high choices too limited.
-
Profile switching is supported through profiles and button combinations, but the underside DPI/profile button placement is sometimes criticized.
-
Side button quality is one of the more mixed areas, with praise for crispness and placement offset by repeated complaints about small size, stiffness, or high placement.
-
Motion consistency is strong in practice through smooth high-polling movement and stable tracking, but MotionSync and ripple controls are not fully configurable.
-
Value is context-dependent: reviewers agree it is expensive, but several justify the price for competitive FPS users while others recommend cheaper alternatives.
-
Scroll wheel quality is mixed: several reviewers praise tactile, quiet, or smooth behavior, while others report average tactility, light resistance, or overscrolling.
-
Grip texture is the most disputed physical trait: some like the ridges or roughened surface, while others call the coating slippery and dependent on grip tape.
-
Click noise is divisive: some reviewers found it quiet and pleasant, while others said the optical switches are louder, hollow, or not suited to silent-click preferences.
Cons
-
Evidence for MMO use is limited but mildly positive where reviewers mention Final Fantasy XIV, Diablo IV, or mapping side buttons for raids; it is not an MMO-first mouse.
-
Software usability is mixed-to-negative: it exposes deep settings, but many reviewers call Armoury Crate bloated, slow, heavy, or inconvenient.
-
Fingertip comfort is mixed: a few reviewers could use it or liked the control, but several said the ergonomic shell is awkward or not recommended for fingertip.
-
Firmware reliability is a minor concern because at least one review described updates as inconvenient and limiting software reconfiguration until completed.
-
Handedness is a clear limitation because the shape is right-handed, with left-handed and ambidextrous users directed elsewhere.
-
Debounce customization is weak because the available evidence says there is no debounce setting or that debounce is not adjustable.
