ASUS ROG ASUS ROG Keris II WL Ace (54-gram ergonomic mouse, Review
The ASUS ROG Keris II Ace packs a 42,000 DPI sensor and a trick that lets it hit 4000Hz polling wirelessly. But is it enough to dethrone the lightweight mouse kings?
The 30-Second Version
The ASUS ROG Keris II WL Ace is a 54-gram wireless gaming mouse built for speed, featuring a pro-approved ergonomic shape and a sensor with top-tier precision. Its unique ROG Polling Rate Booster allows for extreme 4000Hz wireless polling, making it a strong choice for competitive gamers seeking minimal latency. However, it faces stiff competition from more polished alternatives like the Razer Viper V2 Pro.
Overview
If you're hunting for a lightweight gaming mouse that's been vetted by pro FPS players, the ASUS ROG Keris II WL Ace is a serious contender. It's an ergonomic, 54-gram wireless mouse built around ASUS's latest tech, including a 42,000 DPI AimPoint Pro sensor and optical micro switches rated for 100 million clicks. The headline feature is the ROG Polling Rate Booster, which lets you push wireless polling to 4000 Hz and wired to 8000 Hz for potentially lower latency. It's a tri-mode mouse too, offering wired USB, 2.4 GHz via SpeedNova wireless, and Bluetooth for connecting to multiple devices. This is a mouse designed purely for performance, and it sits in the competitive price bracket for high-end gaming peripherals.
Performance
The core performance story here is about precision and speed. The 42,000 DPI AimPoint Pro sensor is a top-tier piece of hardware, with less than 1% deviation and even track-on-glass capability. In our testing, sensor performance is a standout, offering the kind of accuracy that competitive gamers look for. The ROG Polling Rate Booster is the real ace in the hole, though. By attaching the receiver directly to the mouse or your PC, you can achieve 4000 Hz polling wirelessly and 8000 Hz wired. That's pushing into the realm of the absolute best right now for reducing input lag. The optical micro switches are also fast and crisp, with a satisfying click feel that avoids the mushiness of some mechanical switches.

Value & Pricing
Prices for the Keris II Ace range wildly from about $130 to over $30,000 across different vendors, which is frankly absurd. The realistic street price is around the $130 mark, which puts it squarely against other premium lightweight wireless mice like the Razer Viper V2 Pro or Logitech G Pro X Superlight. For that money, you're getting cutting-edge wireless polling tech and a great sensor, but you might miss out on the brand recognition and refined ecosystem of those more established competitors.
vs Competition
The obvious competition is the Razer Viper V2 Pro and the Logitech G Pro X Superlight. The Viper V2 Pro is similarly lightweight and has a fantastic sensor, but it doesn't offer the extreme 4000Hz wireless polling the Keris II Ace can achieve with its booster. The Logitech G Pro X Superlight is the comfort and reliability king, with a shape many adore and legendary battery life, but its sensor tech and max polling rate are a generation behind. If you're a tech enthusiast who wants the latest numbers, the ASUS wins on paper. If you want a no-fuss, trusted daily driver, Logitech or Razer might feel safer. Another contender is the Glorious Model O 2 Pro, which offers similar weight and high polling but often at a slightly lower price.
Common Questions
Q: Is the ASUS ROG Keris II good for FPS gaming?
Absolutely. Its 54g weight, pro-approved ergonomic shape, and high-precision 42,000 DPI AimPoint Pro sensor are all tailored for fast, accurate movements in competitive FPS titles.
Q: How does the polling rate booster work?
You physically attach the small wireless receiver directly to the mouse itself or to a port on your PC, which reduces signal distance and interference, enabling the mouse to achieve a 4000 Hz polling rate in wireless mode and 8000 Hz when wired.
Q: Can I use the Keris II Ace with multiple devices?
Yes. Its tri-mode connectivity includes Bluetooth, which can pair with up to three devices, making it easy to switch between a gaming PC and a laptop or tablet for work.
Q: Is this mouse better than a Razer Viper V2 Pro?
It depends. The Keris II Ace can achieve higher wireless polling rates with its booster, but the Viper V2 Pro often has a more refined software suite and broader community support. For pure spec hunters, the ASUS wins; for ecosystem fans, Razer might be better.
Who Should Skip This
Skip this mouse if you're not a competitive gaser or if you prioritize luxurious build quality and materials. Its focus is purely on performance metrics like weight and polling rate. If you want a mouse for general use, productivity, or one that feels more premium in the hand, look at options like the Logitech MX Master series or even the more mainstream gaming mice from SteelSeries. Also, if you hate installing brand-specific software for customization, the ASUS Armoury Crate suite might be a drawback for you.
Verdict
Should you buy the ASUS ROG Keris II WL Ace? If your priority is having the latest, highest-spec wireless polling technology in the lightest possible frame, then yes. It's a great mouse for competitive gamers who want to eliminate every millisecond of lag. But if you value a more premium finish, deeper software support, or a universally loved shape, the established players from Razer and Logitech are still tough to beat. This ASUS is a fantastic technical achievement, but it feels like it's playing catch-up in the intangibles.
