ASUS ROG Keris II Ace: problems, parts and running costs
Checked: 2026-10-27
Summary
The ROG Keris II Ace is a 54 g right-handed wireless gaming mouse with strong sensor performance and very low click latency, but reviewers and the available data flag a high price, wired-only 8,000 Hz polling, heavy Armoury Crate software, and a duller optical-switch feel. It has no consumables, so yearly running cost is effectively zero beyond electricity. It is competitive near $123-130 and fair value at the $159-159.99 MSRP.
Common problems and fixes
- High price — MSRP $159.00 (PCMag) / $159.99 (Tom’s Hardware, TechPowerUp); reviewers call it expensive. [4][5][6]
- 8,000 Hz wired-only — 8,000 Hz works only over USB; wireless caps at 4,000 Hz, and both require the included ROG Polling Rate Booster; default polling is 1,000 Hz. [4][5][6]
- Heavy software — Armoury Crate Gear requires a per-mouse installer, does not recognize connectivity changes without a restart, and leaves files and services after uninstall. [6][7]
- Duller optical-switch feel — the ROG 100M optical switches feel duller and more muted than mechanical switches, with moderate pre/post-travel. [6]
- Weak default side grips — side grips are grooved plastic rather than rubber; 3M grip tape is included but its adhesive may wear. [7]
- Scroll wheel limitations — the wheel has no free-scroll or L/R tilt, and tactility was average at best on the tested unit. [3][6]
- No left-handed version — the mouse is right-handed only. [5][7]
- Battery life unspecified at high polling rates — ASUS cites up to 107 hours in 2.4 GHz without lighting but does not specify battery life by polling rate. [1][5][6]
Parts and consumables
- Replacement PTFE feet (larger set included) — included in the box; replacement cost and frequency not reported. [4][5][6]
- Grip tape (3M) — included; adhesive may wear over time. [7]
- Internal lithium-ion battery (300 mAh) — rechargeable; replacement cost and availability not reported. [6]
Yearly running cost
Not enough data to compute a yearly running cost: no consumables, filters or subscriptions are reported, and electricity use is not quantified; the 300 mAh battery is rechargeable and replacement cost is unknown. [4][5][6]
When it is a good buy
MSRP $159.00 (PCMag) / $159.99 (Tom’s Hardware, TechPowerUp) at the time of check (October 2026). Retailer snapshots: Best Buy $122.99, Walmart $129.99, Newegg $159.99 (Tom’s Hardware); Walmart $124, Newegg $159 (PCMag). At roughly $123-130 the Keris II Ace is competitive with other high-end lightweight mice while offering 4,000/8,000 Hz polling, very low click latency and strong sensor performance; at $159-160 it is a competent but pricey option against Logitech and Razer flagships; above $160 value weakens unless the specific shape, weight or included polling booster is required. [4][5][6]
Alternatives: the ROG Harpe Ace Aim Lab Edition is the better choice if you prefer the ambidextrous sibling shape; the original ROG Keris Wireless is the predecessor if you want the earlier model. [3][4]
