The ASUS ROG Harpe Ace Aim Lab Edition is a lightweight wireless gaming mouse. It has a symmetrical shape that ASUS co-developed with esports professionals and that they claim ensures maximum stability and control when flicking and tracking. The lightweight body of this mouse is made of what ASUS refers to as 'bio-based nylon,' and under the hood, it uses a top-of-the-line sensor and ROG Micro Switches. This mouse also features software integration with a popular aim trainer, Aim Lab. This integration is supposed to help you find the right settings to use with your mouse to suit your play style.

Test Results
This mouse has a symmetrical shape with a slightly rough, matte black plastic body. There are shallow textured plastic grooves on either side of the mouse for added grip. The two side buttons are colored light blue, and the scroll wheel has an RGB zone. In terms of branding, there's a ROG logo on the palm area, and the word 'ROG' debossed behind the textured side grip grooves on the right side. A small Aim Lab logo on the left side of the mouse towards the front illuminates if you shine your mouse under ultraviolet light.
The ASUS Harpe Ace has impressive build quality overall. However, if you apply considerable pressure, there's a small degree of side wobble in the mouse wheel and minimal flex in the plastic body. Still, it isn't noticeable when using the mouse normally. The plastic body has a slightly rough but pleasant texture for added grip, and the left- and right-click switches have a crisp feel and are light to actuate. The side button closest to the back of the mouse feels slightly mushy. However, this is only noticeable if you forcefully press the side buttons.
This mouse is extremely lightweight in its default configuration. Note that the adhesive grip tape included in the box will add up to a couple of grams to the total weight if used.
This mouse has a comfortable symmetrical shape with a medium-sized hump towards the rear. Overall, it's well-suited for all grip types and best-suited for medium and larger-sized hands. If you have smaller hands, you may have trouble reaching the side buttons without adjusting your grip, and if you have extra-large hands, you'll likely find the grip width feels a bit too narrow.
ASUS advertises the battery life of this mouse at a maximum of 90 hours while connected via its USB receiver and with RGB lighting off or up to 79 hours with default RGB lighting on. It also claims up to 98.5 hours with lighting off while connected via Bluetooth.
This mouse has a lightweight and flexible paracord-like cable. It glides well across desks, but it retains some kinks from how it's packaged.
This mouse has superb rounded feet that glide well on mousepads with minimal resistance. They make a bit of a scratching sound on mousepads and slightly more noticeable scratching sounds when used directly on desks, but this doesn't affect the gliding experience. There's an alternative large mouse foot included in the box that you can use to replace the small two feet at the front of the mouse if you prefer.

You can program nearly all the buttons on the ASUS ROG Harpe Ace, including the scroll up/down inputs. However, you can't reprogram the CPI and Pair buttons on the underside of the mouse, and while you can reprogram the left- and right-click buttons, they need to be assigned to a button at all times.
The left- and right-click buttons use ROG Micro Switches rated for 70 million clicks. While some mice produced by ASUS have hot-swappable switch sockets, this mouse does not.
The ASUS Harpe Ace has incredibly low click latency. It delivers an extremely responsive-feeling experience for gaming in any genre at any competitive level.
This mouse has exceptional CPI performance. Its sensor delivers outstanding tracking accuracy, and the physical movements you make with your mouse translate extremely close to your cursor movements on-screen.
This mouse has remarkable sensor latency. The sensor reacts exceptionally quickly when you move your mouse, and these movements very closely match the timing of your cursor on-screen.
This mouse has polling rate options of 125Hz, 250Hz, 500Hz, and 1000Hz. You can adjust the CPI, polling rate, and lift-off distance directly on the mouse using button combinations listed in the user documentation. Using the customization software, you can also change these settings and several more advanced settings, including angle snapping and acceleration.
The scroll wheel has a lightly grooved rubber grip, and scrolling feels precise. There's a pronounced definition between steps, and scrolling is fairly quiet. The middle click button doesn't require too much force to activate but is a bit heavier, so there's little risk you'll accidentally activate it.
The mouse buttons and scroll wheel on this mouse are on the louder side compared to similar mice. The volume of this mouse may bother people around you if they're particularly sensitive to noise.
This mouse uses Armoury Crate for customization. This software is available for download in two versions: a 'lite version,' which auto-detects connected ASUS devices and automatically installs corresponding software, or a 'full package,' allowing you to select supported devices manually.
This software allows you to customize expected settings, including button assignments, macros, RGB lighting, surface calibration, and power options. You can also adjust sensor settings like CPI, angle snapping, and polling rates.
However, as with software options from other major manufacturers, Armoury Crate is the source of criticism from the broader community. While we didn't experience any issues during the testing of this mouse, many users online criticize this software for being unnecessarily bloated, requiring frequent updates, and taking up disproportionate system resources, among other complaints. This software may be frustrating if you prefer more lightweight software options or no software at all.
This mouse also offers a separate software integration feature with the popular aim training software Aim Lab. ASUS calls this the Aim Lab Settings Optimizer, and they claim it can help you choose what CPI, angle tuning, and lift-off distance settings to use with this mouse to complement your play style.
All default button functions work in Windows and macOS. While the software is only compatible with Windows, you can customize the CPI, polling rate, and lift-off distance directly on the mouse using button combinations listed in the user documentation.
