The ASUS ROG Harpe Ace 2 pushes wireless ultralight performance to new heights at just 49 grams with the PAW3950 sensor and 4KHz polling. Released in 2024, it represents ASUS ROG's most aggressive entry into the competitive ultralight space. The ROG Micro switches deliver crisp actuation in one of the lightest wireless shells from any major manufacturer. ASUS's engineering resources — the same company that builds motherboards, GPUs, and laptops — give the ROG mouse division access to materials science expertise that most peripheral companies lack. The Harpe Ace 2 competes directly with the lightest offerings from Finalmouse and WLMouse while carrying the warranty and support infrastructure of a massive corporation. It demonstrates that ASUS is committed to competing at the cutting edge of mouse performance.
