ROG Keris II Ace Wireless

Overview

The ASUS ROG Keris II Ace Wireless is one of the lightest wireless ergonomic mice available, weighing just 54g while packing ASUS’s top-tier ROG AimPoint Pro sensor based on the PixArt PAW3950. Released in 2023 at $119.99, it represents ASUS’s bid to compete with the Razer DeathAdder V3 Pro in the ultra-light ergonomic wireless category. The result is a technically impressive mouse that checks every specification box while adding unique touches like antibacterial coating and ROG SpeedNova wireless.

At 54g, the Keris II Ace weighs 10g less than the DeathAdder V3 Pro (64g) and matches the Pulsar Xlite V3 Wireless (55g). This is remarkable for an ergonomic mouse from a major brand — getting an ergonomic shape under 55g without a honeycomb shell requires aggressive weight reduction engineering across every component. For right-handed players who want palm or claw grip comfort with minimal weight, the Keris II Ace Wireless earns serious consideration.

The Keris II Ace represents the second generation of ASUS’s gaming mouse line, showing that the company is iterating quickly and learning from the first generation’s feedback. The weight reduction from the original Keris, improved sensor, and refined shape demonstrate genuine product development rather than incremental marketing updates.

Design & Build Quality

The Keris II Ace Wireless measures 120mm x 64mm x 42mm — slightly smaller than the DeathAdder V3 Pro in every dimension (128mm x 68mm x 44mm). The compact footprint makes it better suited for small-to-medium hands than the larger DeathAdder shape. This size positioning is deliberate: ASUS is targeting the segment of ergonomic users who find the DeathAdder slightly too large but still want right-hand ergonomic support.

The shell is PC/ABS with ASUS’s antibacterial matte coating, which resists bacterial growth on the contact surfaces. Whether this provides a meaningful hygiene benefit during daily use is debatable — independent testing of antibacterial mouse coatings shows modest bacterial reduction over standard surfaces. But it contributes to a slightly different surface texture — marginally smoother and more uniform than standard matte coatings, with a clean feel that remains consistent over time.

Build quality is excellent and competitive with the best in the market. The shell has zero detectable flex under grip pressure, the primary buttons are firmly mounted with no wobble, and the overall construction feels tight and precise. ASUS clearly engineered this mouse for durability despite the aggressive weight reduction. There are no visible seams where the shell halves meet, no creaking under pressure, and no rattle when shaken. At 54g, achieving this level of structural integrity requires careful material selection and thickness optimization — ASUS has done this well.

The mouse features a clean design without RGB lighting, keeping the weight down and the aesthetic professional. The top shell has a subtle ROG logo that does not interfere with grip contact or create a raised surface you can feel. The sides have a gentle texture that provides grip assistance without being aggressive or rough on skin.

The bottom shell features a clean layout with the sensor centered and PTFE feet at the four corners. The power switch and connectivity toggle sit on the underside, along with the dongle storage compartment that securely holds the 2.4GHz receiver during transport.

Available primarily in black. The restrained design works well in both gaming and office environments without drawing attention.

Shape & Grip Compatibility

The Keris II Ace Wireless measures 120mm x 64mm x 42mm with a right-handed ergonomic shape. The hump peaks behind center at 42mm — providing meaningful palm support for right-hand grips without the aggressive height of larger ergonomic mice. The right side curves inward to accommodate ring and pinky fingers in a natural resting position, while the left side has a gentle outward flare that creates a comfortable thumb channel. The overall profile is more compact than the DeathAdder V3 Pro, making it better suited for smaller hands — a critical distinction in a market where many ergonomic mice are sized for 19-21cm hands.

Palm Grip (18-20.5cm hands): Palm grip is the primary intended use case. For hands measuring 18cm to 20.5cm in length and 9cm to 10.5cm in width, the ergonomic contour cradles the palm naturally with the rear hump filling the space behind your knuckles. The 42mm hump height provides solid support without forcing your wrist into an extreme angle. The 120mm length is slightly short for hands over 20cm, which may result in your fingertips extending past the button edges — this creates a sensation of reaching for clicks rather than resting on them. Hands between 18cm and 19.5cm will find the fit particularly good — the compact dimensions prevent the overstuffed feeling that larger ergonomic mice can create for medium hands. At 54g, the mouse feels remarkably light during palm grip, almost as if it is not there — a sensation that takes adjustment time if you are coming from heavier ergonomic mice.

Claw Grip (17.5-20cm hands): Claw grip works well, especially in a relaxed claw position where the base of your palm still contacts the rear hump. The ergonomic right-side curve supports your ring and pinky fingers in an angled position that feels natural for claw, and the 54g weight makes micro-adjustments feel effortless — you can redirect the mouse with minimal wrist effort, which reduces fatigue during extended sessions. For hands between 17.5cm and 20cm, relaxed claw grip on the Keris II Ace is comfortable and controlled. The 64mm width provides adequate pinching surface for thumb and ring finger without being so wide that it strains the finger spread. Aggressive claw (minimal palm contact) is possible but the ergonomic shape tends to pull your hand back toward a more relaxed posture — the contours encourage palm contact rather than resist it.

Fingertip Grip: Not ideal. The ergonomic shape is designed to make contact with your palm, which conflicts with fingertip grip’s defining feature of minimal palm contact. The right-side contour assumes your hand is positioned in a specific right-hand orientation, and fingertip grip’s free positioning does not align with this assumption. The 42mm hump also pushes against your palm when you try to lift the rear of your hand away from the mouse. If you strongly prefer fingertip grip, symmetrical mice like the Superlight 2, Viper V2 Pro, or X2 V2 are better suited.

The right-hand-only design means left-handed users should look elsewhere entirely. This is inherent to all right-handed ergonomic mice and not specific to the Keris II Ace. ASUS offers the ROG Harpe Ace for left-handed or ambidextrous users.

Sensor Performance

The ROG AimPoint Pro sensor is based on the PixArt PAW3950 — the successor to the PAW3395 and one of the most capable sensors on the current market. It supports DPI from 100 to 36,000 with maximum tracking speed of 650 IPS and 50g acceleration tolerance. These are best-in-class numbers that match or exceed every competing sensor, including Razer’s Focus Pro 35K and Logitech’s HERO 2.

At competitive DPI settings (400-1600), the AimPoint Pro tracks flawlessly. There is zero detectable jitter, no acceleration, no angle snapping, and perfect consistency across different mousepad surfaces. The 36,000 DPI ceiling is irrelevant for gaming — no competitive player uses DPI above 3200, and most play between 400 and 1600 — but it demonstrates the sensor’s technical headroom and engineering sophistication.

Click latency is approximately 1.5ms with motion latency around 4.5ms — among the lowest in any wireless mouse on the market. These numbers place the Keris II Ace Wireless in the top tier for latency performance, matching dedicated esports mice from Razer and Logitech. The 1.5ms click latency is notably lower than many PAW3395-based mice (typically 1.8-2.0ms), reflecting the PAW3950’s improved processing pipeline.

Lift-off distance is adjustable down to approximately 1.0mm through Armoury Crate software. The sensor handles surface transitions well and does not require calibration for common mousepad materials. The tracking consistency across different pad types (cloth, hybrid, hard) is excellent.

Switches & Buttons

The primary buttons use ROG Micro Switches rated for 70 million clicks. These switches deliver a crisp, defined click with consistent actuation force around 55gf. The click feel is satisfying — sharper and more tactile than standard Omron switches but without the ultralight feel of optical switches. There is a clear tactile break followed by a clean release, which makes rapid clicking comfortable and provides good feedback for timing spray patterns or ability usage in competitive games.

The switches have minimal pre-travel (the dead zone before actuation) and minimal post-travel (the distance after actuation before bottoming out). This tight travel profile makes clicks feel responsive and immediate. Compared to the Kailh GM 8.0 used in Pulsar mice, the ROG Micro Switches have slightly higher actuation force but a similar level of click crispness.

The mouse has five buttons: two primary clicks, scroll wheel click, and two side buttons. The side buttons are positioned at a comfortable height on the left side, accessible for thumb presses without repositioning your hand from palm or claw grip. They have a firm, precise click with minimal mushiness and enough travel to feel deliberate.

The scroll wheel features mechanical steps with a medium, well-defined feel. Each notch is clear enough for precise weapon switching in games, and the scroll movement is smooth enough for comfortable browsing and document navigation. The scroll click requires moderate force — well-calibrated for both gaming and productivity use.

There is no DPI button on the top surface, which contributes to the clean design and prevents accidental DPI changes during gameplay. DPI adjustments are handled through Armoury Crate software or by assigning DPI cycling to a side button through remapping.

Connectivity & Battery

The Keris II Ace Wireless supports tri-mode connectivity: ROG SpeedNova 2.4GHz, Bluetooth 5.1, and wired USB-C. SpeedNova is ASUS’s proprietary 2.4GHz wireless protocol, which provides low-latency performance comparable to Razer HyperSpeed and Logitech LIGHTSPEED. Independent testing confirms that SpeedNova latency is within 0.5ms of competing 2.4GHz implementations — the differences are not perceptible in gameplay.

Battery life is rated at 150 hours on 2.4GHz, with real-world numbers around 95-105 hours depending on polling rate and usage intensity. This is strong — well above the 70-80 hour range of many competitors including the Razer Viper V2 Pro (80h) and the Logitech G Pro X Superlight 2 (95h). The higher battery life allows for less frequent charging, reducing the maintenance burden of wireless mouse ownership.

Bluetooth extends battery life significantly for non-gaming use, making the mouse viable for extended productivity sessions on a laptop without draining the battery quickly. The wired USB-C mode supports play-while-charging with zero additional latency, so you can continue gaming during charging sessions without any performance compromise.

The 2.4GHz dongle stores inside the mouse body for travel convenience, secured by a magnetic compartment that prevents accidental ejection.

Feet & Glide

The Keris II Ace Wireless ships with four large PTFE feet approximately 0.8mm thick. The feet provide a smooth, controlled glide on cloth pads. The larger surface area creates a consistent friction feel rather than the darting, slippery sensation of smaller feet. This controlled glide pairs well with the ergonomic design — palm and claw grip users generally prefer consistent, predictable friction over ultralow friction because it provides better stopping power for precise aiming.

The PTFE quality is good — smooth out of the box with minimal break-in period. The feet maintain their glide characteristics well over months of use before eventual replacement is needed. The 0.8mm thickness provides adequate clearance between the mouse body and pad surface, preventing the bottom shell from catching on thick cloth pads.

Aftermarket feet from Corepad and Tiger Arc are available for users who want to customize their glide characteristics. The standard four-corner foot layout accommodates most aftermarket options designed for the Keris II Ace.

Software

ASUS Armoury Crate handles all configuration for the Keris II Ace Wireless. Features include DPI adjustment (in 50 DPI increments), button remapping for all five buttons, polling rate selection (125/250/500/1000Hz), lift-off distance calibration, and connectivity mode management. The mouse supports five onboard memory profiles, which is generous and lets you store complete configurations for different games or use cases directly on the mouse.

Armoury Crate is ASUS’s unified peripheral management software, and it carries the same reputation issue across all ROG products: it is functional but bloated. The software installs system-level services that run at startup, occupies significant system resources (both RAM and CPU), and can be difficult to fully uninstall once installed. Some users report conflicts with other software or unexpected behavior during Windows updates.

For users who prefer lightweight software, the five onboard memory profiles provide a practical workaround: install Armoury Crate, configure all your profiles, save them to the mouse’s onboard memory, and then remove the software entirely. The mouse retains its settings and functions normally without the software running.

The software itself works well once installed — DPI adjustment, button remapping, and profile management are intuitive with a clear interface. The issue is the overhead, not the functionality.

Pro Player Usage

The ASUS ROG Keris II Ace Wireless has no known professional esports adoption at the highest levels. Despite its excellent specifications and lightweight design, the mouse competes in a space dominated by the Razer DeathAdder V3 Pro and Pulsar Xlite V3 in professional ergonomic mouse selection. These competitors have years of tournament history and community trust that the Keris II Ace has not yet accumulated.

The lack of pro adoption is primarily a brand positioning issue rather than a performance limitation. ASUS does not have the same esports sponsorship infrastructure as Razer or Logitech — they sponsor teams for systems and monitors, not peripherals. This means fewer professional players receive ROG mice through team deals, and without initial exposure, organic adoption is rare.

For specification-driven buyers, the absence of pro validation should not be a deterrent. The hardware speaks for itself: the PAW3950 sensor, 1.5ms click latency, 54g weight, and build quality are all objectively competitive with pro-used mice. The Keris II Ace does not perform worse than the DeathAdder V3 Pro — it simply has less competitive heritage behind its name.

Verdict & Buying Guide

Buy if: You want the lightest wireless ergonomic mouse with a top-tier sensor from a major brand. At 54g, the Keris II Ace Wireless undercuts the DeathAdder V3 Pro by 10g while matching or exceeding it on sensor specs and latency numbers. It is also a natural choice for ROG ecosystem users who want a matching peripheral. The antibacterial coating and tri-mode connectivity add practical value that competitors at this price do not offer. If you have hands between 18-19.5cm and prefer palm or relaxed claw grip, the compact ergonomic shape will fit well.

Skip if: You want maximum competitive validation and pro-proven equipment with tournament heritage. The DeathAdder V3 Pro has far more tournament history and pro adoption — it is the safer choice if community validation matters to your purchase decision. If you dislike Armoury Crate and prefer lightweight software, the Pulsar Xlite V3 Wireless ($89.99) offers a similar weight with dramatically simpler software at a lower price.

Alternatives:

• Razer DeathAdder V3 Pro ($149.99): More pro-proven ergonomic shape with decades of competitive heritage. 64g weight, Focus Pro 30K sensor. The established champion of lightweight wireless ergonomics.
• Pulsar Xlite V3 Wireless ($89.99): Similar weight (55g), $30 cheaper, PAW3395 sensor, minimal software. Better value for budget-conscious ergonomic shoppers.
• ASUS ROG Harpe Ace Aim Lab Edition ($99.99): Same brand, symmetrical shape at 54g, for those who prefer ambidextrous design over ergonomic.

At $119.99, the Keris II Ace Wireless is competitively priced for its specifications. The 54g weight and PAW3950 sensor are best-in-class for ergonomic wireless mice. Whether the ASUS brand and Armoury Crate software are acceptable trade-offs depends on your tolerance for software overhead and your preference for brand heritage versus pure specifications.
