It starts at 56g with stackable weights, and drops RGB entirely for a desk-mounted 8K receiver." categories: - "Mouse, Touchpad & Keyboard" - Review tags: - Asus - Asus ROG - Asus ROG Gladius - gaming mouse - mouse - wireless mouse --- Asus ROG sent me the [Asus ROG Gladius IV Ace Gaming Mouse](https://rog.asus.com/mice-mouse-pads/mice/ergonomic-right-handed/rog-gladius-iv-ace/) as a review unit ahead of its launch. The recommended retail price (RRP) is **S$239**. Although it comes in Moonlight White, Lava Red, and Aqua Blue, only Black and White are available in Singapore. You can get it from [Shopee](https://s.shopee.sg/8fTCGZoy3v) or [Lazada](https://s.lazada.sg/s.6CoVM). I have been using the [Asus ROG Keris II Ace](https://lesterchan.net/blog/2024/05/02/asus-rog-keris-ii-ace-gaming-mouse-review/) and the [Asus ROG Keris II Origin](https://lesterchan.net/blog/2025/12/22/asus-rog-keris-ii-origin-gaming-mouse-review/), and this is a different animal. It runs the ROG AimPoint Pro 65K sensor at up to 65,000dpi with true 8,000Hz polling, wired or wireless, and it is built for competitive players with larger hands.

[![Asus ROG Gladius IV Ace Gaming Mouse - Weights](https://live.staticflickr.com/65535/55509700952_41548c156a_c.jpg)](https://live.staticflickr.com/65535/55509700952_65cfe06d98_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Weights") [![Asus ROG Gladius IV Ace Gaming Mouse - Mouse Grip And Feet Tape Set](https://live.staticflickr.com/65535/55510817308_5168176ced_c.jpg)](https://live.staticflickr.com/65535/55510817308_2300af06ef_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Mouse Grip And Feet Tape Set") [![Asus ROG Gladius IV Ace Gaming Mouse - Pick And Weights Screw](https://live.staticflickr.com/65535/55510863189_4433ca6616_c.jpg)](https://live.staticflickr.com/65535/55510863189_4e9c15abd1_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Pick And Weights Screw") [![Asus ROG Gladius IV Ace Gaming Mouse - Carrying Case](https://live.staticflickr.com/65535/55510817293_d77f4d1825_c.jpg)](https://live.staticflickr.com/65535/55510817293_359d588dae_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Carrying Case") ## Design This is probably my favorite Asus ROG mouse so far because it fits my large hand nicely. Both the Keris II Ace and Keris II Origin measure 121 x 67 x 42mm, while the Gladius IV Ace is 127.5 x 67.7 x 44.15mm. That is 6.5mm longer and 2.15mm taller. [![Asus ROG Gladius IV Ace Gaming Mouse - Top](https://live.staticflickr.com/65535/55510708786_054a15de19_c.jpg)](https://live.staticflickr.com/65535/55510708786_e510b88f4f_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Top") Asus calls it a wider palm rest and a taller rise. In practice, my palm reaches the back of the mouse instead of hanging past the tail, and rests on the shell rather than arching above it. The shell is matte and lacks a rubber coating, but Asus offers the option to stick the Mouse Grip Tape if you need more friction. [![Asus ROG Gladius IV Ace Gaming Mouse - Left](https://live.staticflickr.com/65535/55509700887_99479089b3_c.jpg)](https://live.staticflickr.com/65535/55509700887_b37da4bdfa_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Left") [![Asus ROG Gladius IV Ace Gaming Mouse - Right](https://live.staticflickr.com/65535/55510817263_79c93084d4_c.jpg)](https://live.staticflickr.com/65535/55510817263_b40a9909bc_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Right") The scroll wheel is smoother than the Keris II’s, with lighter, less notchy steps. Nicer for long scrolls, harder if you count clicks to swap weapons. [![Asus ROG Gladius IV Ace Gaming Mouse - Front](https://live.staticflickr.com/65535/55510817253_6c8b3f1798_c.jpg)](https://live.staticflickr.com/65535/55510817253_fc1302b238_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Front") USB-C is in front. At the bottom are two large PTFE feet, the DPI button, and a three-position slider for Bluetooth, off, and 2.4GHz RF. [![Asus ROG Gladius IV Ace Gaming Mouse - Bottom](https://live.staticflickr.com/65535/55511081390_2db4b7a11b_c.jpg)](https://live.staticflickr.com/65535/55511081390_7d52fcf86b_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Bottom") ## Switches It uses the ROG 100M Optical Micro Switch, the same switch family as the Keris II Ace, not the Origin. The Origin uses the ROG Micro Switch II with the Push-Fit Switch Socket II, which is hot-swappable. [![Asus ROG Gladius IV Ace Gaming Mouse - Opening With Pick](https://live.staticflickr.com/65535/55510708761_4effc59c6c_c.jpg)](https://live.staticflickr.com/65535/55510708761_a56896d0ec_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Opening With Pick") Opening the mouse is easy. Peel off the two rubber covers at the bottom, undo the two screws, and run the included ROG pick around the seam. [![Asus ROG Gladius IV Ace Gaming Mouse - Opened](https://live.staticflickr.com/65535/55511081370_c5fa336696_c.jpg)](https://live.staticflickr.com/65535/55511081370_6ca5981ffd_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Opened") Since Asus includes the pick, they expect you to open the mouse often. Yet the switches are soldered onto the board and not hot-swappable. [![Asus ROG Gladius IV Ace Gaming Mouse - Switches](https://live.staticflickr.com/65535/55511081345_c3b7c8c46e_c.jpg)](https://live.staticflickr.com/65535/55511081345_7c7c2e952f_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Switches") Asus matches the left and right switches at the factory, so both buttons feel identical. Asus optimized this for esports players who need the click to be identical in every round of a match. The click also feels more muted than the Keris II. By muted, I mean lower-pitched and shorter. The Origin gives a bright snap, while this one gives a duller thud that stops the moment the button bottoms out. Travel is similar; it is the sound that differs. ## Weights The mouse starts at 56g. The weights are 3g, 5g, and 7g, usable in any combination, giving eight configurations up to 71g. [![Asus ROG Gladius IV Ace Gaming Mouse - Without Weights](https://live.staticflickr.com/65535/55509700837_b4a7967611_c.jpg)](https://live.staticflickr.com/65535/55509700837_c05ef49396_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - Without Weights") They stack into a tray under the palm hump, with a screw to hold them down so nothing rattles. [![Asus ROG Gladius IV Ace Gaming Mouse - With Weights](https://live.staticflickr.com/65535/55510863024_5a4d70ba57_c.jpg)](https://live.staticflickr.com/65535/55510863024_431f92372f_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - With Weights") The Keris II Ace is 54g, and the Origin is 65g, so I settled on the 5g, which comes to 61g, right between the two. ## ROG SpeedNova 8K Gen II Receiver This is the second-generation ROG SpeedNova 8K receiver, so instead of a dongle, you get a weighted puck on a cable that sits on your desk. It even comes with a silicone cover to protect it and is fitted out of the box. [![Asus ROG Gladius IV Ace Gaming Mouse - ROG SpeedNova 8K Gen II Receiver](https://live.staticflickr.com/65535/55510817318_f1b5cdb212_c.jpg)](https://live.staticflickr.com/65535/55510817318_e558f75862_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - ROG SpeedNova 8K Gen II Receiver") With the ROG Omni Receiver on the Keris II Ace, I just let the dongle extender dangle off the back of my computer. This one sits right in front of me, which also puts it closer to the mouse. [![Asus ROG Gladius IV Ace Gaming Mouse - ROG SpeedNova 8K Gen II Receiver - Back](https://live.staticflickr.com/65535/55510863154_1d1edda1a9_c.jpg)](https://live.staticflickr.com/65535/55510863154_40c401b89f_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - ROG SpeedNova 8K Gen II Receiver - Back") It earns that desk space because you choose what each of the two front LEDs shows. [![Asus ROG Gladius IV Ace Gaming Mouse - ROG SpeedNova 8K Gen II Receiver - LED Indicators](https://live.staticflickr.com/65535/55510863019_3dd65f8c0a_c.jpg)](https://live.staticflickr.com/65535/55510863019_6989569794_o.jpg "Asus ROG Gladius IV Ace Gaming Mouse - ROG SpeedNova 8K Gen II Receiver - LED Indicators") I left it to the default, which is the left for Battery Power and the right for Wireless Transmission Power. [![Asus Gear Link - Receiver Settings](https://live.staticflickr.com/65535/55510756781_09a9618d69_c.jpg)](https://live.staticflickr.com/65535/55510756781_3d25a88dd2_o.png "Asus Gear Link - Receiver Settings") It also runs RF Smart Detection in 2.4GHz mode, hopping channels to find a clean one and rating the signal from Poor to Excellent. Mine sits at Excellent, no surprise at home. This one is really for a LAN event. ## No RGB There is no RGB at all, and Asus does not list Aura Sync support for it. Probably, RGB isn’t needed for esports players. [![Asus Gear Link - Zone Mode](https://live.staticflickr.com/65535/55511130525_374d128d85_c.jpg)](https://live.staticflickr.com/65535/55511130525_4433d7ba89_o.png "Asus Gear Link - Zone Mode") Asus has not said why, but lighting costs weight and battery, and this mouse is chasing 56g and true 8K wireless. As a semi-RGB lighting enthusiast, I do miss it, since my keyboard lights up and my mouse does not. ## Gear Link [Gear Link](https://gearlink.asus.com/) is Asus ROG’s browser-based configuration tool, which I first used on the Keris II Origin and again on the [Strix Morph 96](https://lesterchan.net/blog/2026/06/04/asus-rog-strix-morph-96-wireless-gaming-keyboard-review/). [![Asus Gear Link - Performance](https://live.staticflickr.com/65535/55510756766_af3e5a67dc_c.jpg)](https://live.staticflickr.com/65535/55510756766_c906fdb925_o.png "Asus Gear Link - Performance") Performance holds the four DPI slots you cycle with the DPI button, defaulting to 400, 800, 1,600, and 3,200. I top out around 3,200dpi, so 65,000dpi is a spec-sheet number to me. [![Asus Gear Link - Calibration](https://live.staticflickr.com/65535/55509747837_c4e0649ae9_c.jpg)](https://live.staticflickr.com/65535/55509747837_e3d60e3498_o.png "Asus Gear Link - Calibration") Power is where you set the sleep timers. Asus does not publish a battery life figure for this mouse, only that SpeedNova 8K Gen II is more efficient than the previous generation. [![Asus Gear Link - Power](https://live.staticflickr.com/65535/55510911624_16dc8b4984_c.jpg)](https://live.staticflickr.com/65535/55510911624_6841656208_o.png "Asus Gear Link - Power") Button Assignment remaps the six buttons, and SpeedShift turns one into a shift key that swaps to a second sensitivity while held, at the cost of that button’s original function. [![Asus Gear Link - Button Assignment](https://live.staticflickr.com/65535/55511130420_326411a987_c.jpg)](https://live.staticflickr.com/65535/55511130420_c1584e40a0_o.png "Asus Gear Link - Button Assignment") [![Asus Gear Link - Speed Shift Settings](https://live.staticflickr.com/65535/55509747822_823bb2609c_c.jpg)](https://live.staticflickr.com/65535/55509747822_06b60f16c5_o.png "Asus Gear Link - Speed Shift Settings") Zone Mode is the competition profile: 2.4GHz-only, with its own sensitivity, polling rate, sensor frame rate cap, and transmission power. Scenario Profiles is the odd one out. It switches your device profile automatically when you launch a game, and the page is really a window into Armoury Crate rather than a Gear Link feature of its own. [![Asus Gear Link - Scenario Profiles](https://live.staticflickr.com/65535/55510865218_e01a7e4ded_c.jpg)](https://live.staticflickr.com/65535/55510865218_9e645c5c36_o.png "Asus Gear Link - Scenario Profiles") ## Conclusion The Gladius IV Ace is the first ROG mouse that actually fits my hand, and if it were mine, it would stay on my desk. Sadly, I have to return this review unit and go back to my Asus ROG Keris II Origin. At least I still have RGB! If you actually play competitively, most of what I flagged above becomes a non-issue. No RGB saves weight and battery, which you would rather spend elsewhere. The soldered switches keep both buttons feeling identical. The weights let you settle on a number and leave it there. The carrying case and the desk receiver with its RF Smart Detection are built for a venue full of wireless gear, which I cannot test at home. For that audience, this is the most coherent mouse Asus has put together. Coming from the Keris II Ace, this is a clean upgrade. The Ace has no hot-swap either and only lights its scroll wheel, so you give up nothing and gain the larger shape, the desk receiver, and 8,000Hz wireless instead of 4,000Hz. From the Origin, it is a trade rather than an upgrade. You get the shape and 8,000Hz without buying the Polling Rate Booster separately, but you lose hot-swappable switches and three RGB zones. Worth it only if the bigger shell is what you are after. Nitpick: I still wish the switches were socketed. I know why Asus did it, and matched click feel matters more to a pro than a mouse that lasts five years. For the rest of us, it is the other way round, though at 100 million clicks, I will probably want a new mouse before these wear out.
