Compare Endgame Gear XM2we vs ASUS ROG Keris II Ace

Reviewers confirm 2.4GHz wireless or dongle-based wireless, with no connection-drop complaints in supported reviews.

Reviewers consistently find the tri-mode setup useful, with 2.4GHz wireless treated as the main gaming connection and Bluetooth/USB adding flexibility.

Sensor specs and reviewer usage support strong acceleration handling for fast flicks, though it is discussed as capability rather than a separate tuning feature.

The sensor's 50g acceleration rating is repeatedly cited as part of its top-tier performance spec, with no practical complaints about acceleration handling.

Tracking is consistently described as accurate, with reviewers praising the PAW3370 implementation even during fast movement.

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.

Most reviewers found the mouse well balanced or stable, with a few noting it can feel slightly rear- or side-heavy compared with lighter rivals.

Most reviewers praise the balance as centered and easy to control, but one detailed teardown-style review found a slight forward bias.

Battery life is generally good, ranging from about 48 hours to more than a week, with several reviewers reporting week-plus use.

Battery life is generally considered strong at normal wireless settings, though several reviewers note high polling rates and RGB reduce runtime.

Bluetooth evidence is mixed: one review says Bluetooth is present, while another explicitly says the mouse lacks Bluetooth support.

Bluetooth is a well-liked convenience feature, especially for multi-device and non-gaming use, while reviewers still favor 2.4GHz for competitive play.

Build quality is one of the strongest themes, with reviewers repeatedly calling the chassis solid, tight, robust, or excellent.

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.

Button reassignment is supported in software, and reviewers found basic remapping straightforward even if the software is minimal.

Button remapping and control customization are well supported through Armoury Crate or onboard controls, including DPI, polling, and command assignment.

Responsiveness is praised in use, especially in gaming, with no delays or misfires reported by the strongest positive reviews.

Button responsiveness is broadly positive, with reviewers calling clicks snappy, low-latency, precise, or consistent, even when switch feel is debated.

The cable is generally flexible or thoughtfully angled for charging and wired use, though one reviewer found it stiff.

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.

Charging is easy and play-and-charge use is supported, with one review reporting a very fast full charge and others noting a two-hour estimate.

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.

The XM2we is most consistently praised as a claw-grip mouse, especially for medium to large hands and aggressive claw styles.

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.

Click latency evidence is positive overall, with adjustable debounce and several reviewers reporting no laggy click latency.

Measured and reported click latency is very low, with reviewers citing roughly 1ms or sub-millisecond behavior depending on mode.

Click noise is a drawback in the one review that directly discusses it, describing the buttons as loud.

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.

Connection stability is strong in direct reports, with reviewers noting no drops, lags, hiccups, or similar wireless problems.

Connection stability is a major strength, with reviewers repeatedly reporting no dropouts, no stutters, no hiccups, and stable high-polling wireless use.

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.

Debounce adjustment is repeatedly supported, including settings down to zero milliseconds in software.

Debounce customization is weak because the available evidence says there is no debounce setting or that debounce is not adjustable.

The PAW3370 sensor supports a high 19,000 CPI range, which reviewers present as enough for competitive shooter use.

The 42,000 DPI ceiling is repeatedly highlighted as class-leading, though reviewers often note most players will never use the upper range.

Drag-click support is directly praised in one review, which found the grippy coating and button travel unusually strong for high CPS.

Durability evidence comes mainly from optical-switch design, no double-click issues, and switch ratings rather than long-term ownership.

Durability evidence centers on optical switches, double-click resistance, consistent performance over time, and serviceability such as hot-swappable switches.

Ecosystem integration is positive through Aura Sync, Windows Dynamic Lighting mentions, and the ROG Omni Receiver's ability to pair with other ROG peripherals.

Ergonomic evidence centers on the shape, thumb-access side buttons, low button height, and stability for claw-oriented grip styles.

The right-handed ergonomic design is a core strength, frequently described as comfortable, esports-focused, and well-shaped for palm or relaxed claw use.

Fingertip comfort is mixed to weak, with reviewers saying the mouse is wide or not ideal for fingertip grip unless the hand size fits.

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 evidence is limited but positive to mixed: reviewers report adequate firmware performance and mention updates addressing reported issues.

Firmware reliability is a minor concern because at least one review described updates as inconvenient and limiting software reconfiguration until completed.

FPS suitability is a clear strength, with multiple reviewers testing or recommending it for shooters and fast aim-heavy play.

FPS suitability is excellent, with reviewers repeatedly tying the mouse to esports, Valorant, Counter-Strike, and high-speed competitive aim.

Glide is a major strength on suitable pads, repeatedly described as smooth, fluid, or excellent, though some hard or soft pad edge cases appear.

Glide is consistently praised thanks to smooth PTFE feet, spare feet, and strong performance on cloth, glass, and other surfaces.

Grip texture is divisive: many praise the coating as grippy, while others find it slippery, dirty-looking, or lacking enough grip.

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.

The side-button layout and shape make this effectively a right-handed mouse, with no left-handed option discussed.

Handedness is a clear limitation because the shape is right-handed, with left-handed and ambidextrous users directed elsewhere.

Left and right clicks are generally praised for crisp optical feel, though some reviewers found them heavy or uneven.

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.

Lift-off distance is adjustable, with reviewers citing 2mm stock behavior and a 1mm option through software.

Lift-off distance is adjustable but not universally loved; reviewers liked having the control, while some found the low/high choices too limited.

Long-session evidence is positive but limited, with one review emphasizing low strain over extended use.

Long-session comfort is mostly strong due to low weight and ergonomic support, though some hand sizes reported cramps or fit issues.

Macro support is present in the companion app according to PC Gamer, though only one review discusses it directly.

Macro support exists through Armoury Crate, but it is not a headline strength and onboard macro behavior is more limited.

Material evidence supports a thick plastic chassis and matte coating that reviewers generally describe as high quality.

Materials quality is mixed-positive: the nylon/PBT construction supports low weight and rigidity, but coating feel and premium texture divide reviewers.

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.

Motion consistency is strong in direct testing, including stable polling-rate behavior and no noticeable latency comments.

Motion consistency is strong in practice through smooth high-polling movement and stable tracking, but MotionSync and ripple controls are not fully configurable.

Onboard profiles are directly supported in Tom’s Hardware, which says saved profiles can be used without installing software.

Onboard memory and onboard controls are meaningful positives, with reviewers citing hardware profiles, on-device controls, and software-free settings changes.

Palm comfort is workable but not the main target; some reviewers liked it for palm grip, while others said the shape favors claw.

Palm grip comfort is a major strength for small-to-medium or relaxed palm users, though very large hands may prefer bigger ergonomic mice.

Polling-rate support is repeatedly mentioned, with 1,000Hz behavior described as responsive or stable.

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.

Portability is mixed because it is wireless and light, but lack of dongle storage or Bluetooth limits travel/laptop convenience.

Portability is helped by Bluetooth, dongle storage, multi-device use, and travel-friendly wireless operation, even if the booster setup can be bulky.

Premium feel is repeatedly tied to the coating, build, quality, and overall hand feel despite the no-frills feature set.

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.

Profile switching is supported through onboard profiles or the bottom mode button, but its underside placement limits on-the-fly use.

Profile switching is supported through profiles and button combinations, but the underside DPI/profile button placement is sometimes criticized.

Programmable buttons are present in a simple five-button layout with an extra underside button in one review.

Programmable button coverage is solid for an FPS mouse, typically five or six physical buttons plus scroll directions through software.

RGB features are intentionally absent; reviewers often treat the no-RGB design as a no-frills choice, but the feature score is low.

RGB is limited to the scroll wheel but appreciated because many ultralight esports mice omit lighting entirely; some reviewers dislike the execution.

Scroll-wheel quality is mixed but mostly good, with praise for stiffness, tactility, and defined steps plus some complaints about rigidity.

Scroll wheel quality is mixed: several reviewers praise tactile, quiet, or smooth behavior, while others report average tactility, light resistance, or overscrolling.

Sensor performance is consistently solid to excellent, despite several reviewers noting the PAW3370 is older than newer 3395-based rivals.

Sensor performance is a standout strength, with the AimPoint Pro repeatedly described as accurate, high-spec, smooth, and reliable.

Shape comfort is strong for XM1 fans and claw grip, but less safe for smaller hands or non-claw grip styles.

Shape comfort is broadly positive, especially for small-to-medium ergonomic users, but fit varies by hand size and grip preference.

Side-button quality is one of the most consistent positives, with repeated praise for placement, tactility, and low travel.

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.

Skate durability evidence is limited but positive, with one reviewer reporting the stock skates held up well and no dust or grinding on glass.

Software stability is mixed: the app is simple and works for configuration, but battery reporting is criticized as unreliable.

Software stability is acceptable in the lighter Armoury Crate Gear experience, but broader Armoury Crate concerns remain around bloat and background processes.

Software usability is strong overall because the tool is simple, light, and focused on essentials rather than bloat.

Software usability is mixed-to-negative: it exposes deep settings, but many reviewers call Armoury Crate bloated, slow, heavy, or inconvenient.

Surface compatibility is good overall, but reviewers note the glide behaves best on suitable soft pads and may feel rough on hard pads.

Surface compatibility is excellent, with reviewers citing glass tracking, surface calibration, and reliable behavior across mouse pads, tables, and other surfaces.

Switch durability is supported by optical-switch advantages, rated click life, and lack of accidental double-clicking.

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.

Switch feel is broadly good but not universally loved because reviewers split between crisp, tactile praise and complaints about heaviness.

Switch feel is mixed-positive: many like the crisp optical clicks, but some find them mushy, hollow, heavier, or less satisfying than mechanical alternatives.

Tilt controls are essentially absent because the middle mouse button lacks left/right tilt switches.

Value is broadly positive around $79.99 or £80, though PC Gamer considered it less automatic against cheaper competitors.

Value is context-dependent: reviewers agree it is expensive, but several justify the price for competitive FPS users while others recommend cheaper alternatives.

Water and dust resistance is only lightly supported by the hole-free shell comment, not by any formal IP rating or test.

Weight is consistently light at roughly 62-65g, though some reviewers compare it unfavorably with 55g competitors.

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.

Wireless latency evidence is strong, with reviewers reporting no noticeable latency or very low measured motion/click latency.

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.

Wireless performance is consistently strong, with reviews reporting smooth play, no dropouts, and no meaningful wired/wireless difference.

Wireless performance is excellent overall, with stable 4,000Hz operation, no dropouts, and strong sensor performance frequently reported.
