Introduction & Specification Details and Close-up

Late last year, we reviewed ASUS's ROG Harpe Ace Extreme wireless gaming mouse, which was pricey, but also one of the most impressive mice you'll encounter. From its high-end sensor to the carbon fiber shell, you could say the design was a bit over-the-top, but then again, it's always cool to see peripherals and products go all-out like they're a fine Italian sports car. The new ASUS ROG Keris II Origin Wireless Gaming Mouse is a little more down-to-earth, but it's still a premium option for gamers.

The ROG Keris II Origin features a right-handed ergonomic shape with three zones of RGB lighting and a heavier yet ultralight build of approximately 65 grams. It also arrives with a price point that is a little easier on the old wallet. What the new ROG Keris II Origin shares in common with the ROG Harpe Ace Extreme is that it comes equipped with ASUS's latest and greatest optical sensor, the ROG AimPoint Pro.

This not only allows the mouse to track on a wide range of surfaces, including glass, but it features some of the highest specs you're likely to find on a wireless gaming mouse - a sensitivity of 42,000 DPI, 750 IPS tracking, and 50G acceleration. Arguably overkill, but there's no denying that if you do end up picking up an ASUS ROG Keris II Origin Wireless Gaming Mouse, it's a peripheral that will last you several years of gaming.

Also, it's worth highlighting that in a sea of symmetrical lightweight FPS and competitive gaming mice, all sporting the same look and feel, it's refreshing to have one show up with a more ergonomic build, RGB flourishes, and fantastic additional items like a set of grip tape for those that want a more comfortable grip, replacement switches for the left-and-right click buttons, and a flexible paracord USB cable so even when it's plugged in you've the same freedom and smooth movement of using the device in wireless mode.

Design, Sensor, & Software

Design

The ASUS ROG Keris II Origin Wireless Gaming Mouse features RGB lighting that covers three zones: the scroll wheel (which we find to be smoother than the more premium ROG Harpe Ace Extreme), the area underneath the side buttons, and the ROG logo on the palm rest. Weirdly, even though you're looking at a peripheral with three RGB lighting zones, it's only one single zone, as there's no way to make individual changes to each zone.

As mentioned in the introduction, although the ROG Keris II Origin resembles a FPS or competitive gaming mouse, it adopts a more traditional right-handed ergonomic shape, which is more comfortable for extended gaming sessions when using a palm grip. Compared to a symmetrical mouse, the ergonomic bump on the ROG Keris II Origin offers a more natural resting position for fingers.

19

RGB will always be an unessential addition to any piece of gear, but here you're still looking at around 82 hours of use with the standard 50% brightness mode over the low-latency 2.4 GHz wireless connection. This shoots up to 127 hours with the lighting turned off, which isn't as drastic a difference as you'd find in other devices. The ROG Keris II Origin features tri-mode connectivity, allowing you to switch between 2.4 GHz wireless, USB wired, and Bluetooth connections. There's a spot on the underside of the mouse to house the dongle, which adds to its versatility by allowing it to be used across multiple devices.

In addition to being comfortable to hold due to the durable PBT finish, the left and right-click buttons have a satisfying, snappy feel, making a notable 'click' sound when pressed. Weighing in at 65 grams, it's not the lightest mouse on the market, but it still falls into the ultralightweight category of mice built for fast movement and competitive gaming. As a fan of grips on a mouse, it's always great to see grip tape included in the package, which ASUS packs into the ROG Keris II Origin's box in addition to replacement PTFE feet and even a couple of spare ROG Micro Switch II switches.

It's quite the package. However, there is one thing missing. Even though you're looking at a high-end mouse with seemingly all the bells and whistles, to access the ultra-low-latency 8K or 8,000 Hz Polling Rate (you're limited to the standard 1,000 Hz out of the box), you'll need to shell out for the ROG Polling Rate Booster, which is sold separately.

Sensor

The ROG AimPoint Pro optical sensor is a beast, and not just because it boasts a seemingly ridiculous 42,000 DPI rating. It supports smooth tracking on multiple surfaces, including glass, with accuracy and tracking speeds that are only available on the most powerful premium sensors available today. And yes, for this review, we tested the ASUS ROG Keris II Origin Wireless Gaming Mouse's tracking on a glass coffee table, and it worked flawlessly. ASUS notes that the accuracy features a deviation of less than 1%, which is impressive.

19

The 750 IPS rating is also right up there with the very best, which denotes the 'inches per second' the ROG AimPoint Pro optical sensor can track, which, when paired with the 50G acceleration, means you've got a mouse that will have no issue tracking fast movement or flick shots.

Software

ASUS has enhanced its customization and software support for its ROG peripheral lineup, making the ASUS ROG Keris II Origin Wireless Gaming Mouse one of the most robust and versatile peripheral releases from the company in a long time. You've got the usual Armoury Crate support, which is ASUS's one-stop app for all hardware customization, monitoring, and updates, with the additional option of using the new web-based Gear Link utility for customization. The latter doesn't require any software installation, while giving you the same set of powerful customization tools and features.

19

When it comes to ROG Keris II Origin button assignments, you can make changes to everything apart from the left-click. This includes everything from keyboard assignments to turning the scroll wheel into the volume dial for audio. It's a simple and intuitive setup where all you need to do is select the button and then choose from a corresponding list of categorized functions and assignments on the right. The Armoury Crate and the web-based Gear Link also include the option to adjust the color-coded DPI profiles in increments of 50, while offering the ability to calibrate the sensor for different surfaces manually.

19

With three RGB lighting zones, you've also got the option to fine-tune the lighting on the ROG Keris II Origin or have it sync up with all your other devices. All in all, it's a comprehensive set of options that also includes the ability to adjust the sleep settings and modify the point at which the mouse alerts you that it's running out of juice with a red light.

Gaming Performance and Productivity

Gaming Performance

With its lightweight build, advanced sensor, and ergonomic right-handed palm grip shape, the ROG Keris II Origin is built for all types of PC gaming, including fast-paced competitive shooters like Call of Duty: Black Ops 6 and DOOM: The Dark Ages. After using the mouse for over a week, we tested its gaming performance using these titles, alongside Diablo 4 and Marvel Rivals. In wired or low-latency wireless mode, the 1,00 Hz polling, responsiveness, accuracy, and more all felt identical and flawless.

19

As someone who prefers a palm grip over a claw grip, the ergonomic shape of the ROG Keris II Origin felt more natural and comfortable for longer sessions than using a symmetrical mouse. Side button placement, although fine, is slightly higher than what you'd find on a symmetrical mouse due to the higher ergonomic bump, which required some adjustment to get used to. Outside of that, performance during our time with the ROG Keris II Origin was flawless and impressively smooth.

Productivity

With tri-mode connectivity, the ASUS ROG Keris II Origin Wireless Gaming Mouse serves as a comfortable day-to-day driver, compatible with a wide range of devices. If you plan to use it in a quiet office environment, note that the left and right 'click' sounds are snappy and louder than most mice. Over Bluetooth, you've also got up to 192 hours of battery life, which is more than enough to carry you through a couple of weeks or more of heavy use. Plus, being able to track on just about any surface means that you won't run into any of those situations where you need to find a magazine or piece of matte paper to be able to use your mouse with your laptop.

Final Thoughts

The new ASUS ROG Keris II Origin Wireless Gaming Mouse is the company's latest offering, and it's just about flawless, with very few major issues or criticisms. The big one would be tying 8K polling to a sold-separately dongle, but 8,000 Hz polling isn't a deal breaker for most gamers and enthusiasts. The other option would be the "three-zone" RGB lighting, which is actually a single zone that you can customize. Ultimately, though, it's a winner. The physical design is impressively solid, the hardware components are premium, and the features are impressive. From the fantastic sensor to tri-mode connectivity to being able to customize the mouse via your browser, software-free.

19

Weighing in at 65 grams, it's also lightweight enough to be considered a fast and performant FPS gaming mouse, albeit one built for those who prefer a right-handed palm grip. Unless you're all about the claw grip, the ROG Keris II Origin comes highly recommended, as it's the sort of mouse that will carry you through several generations of PC hardware.
