The ROG Harpe Ace is engineered through collaboration with the top esports professionals and world record aimers at Aim Lab. Extensive insight and understanding on the needs of esports players has led our designers and engineers to design 15 different versions of the ROG Harpe Ace, until the delicate balance of shape and weight distribution is achieved. Loaded with a sleek form factor and ultra specifications, it is astounding that the Harpe Ace weighs only 54 grams all the while retaining a durable structure that encompasses components to streamline every players journey to excellence. The 36,000-dpi ROG AimPoint optical sensor features 1% cpi deviation, allowing you to track and flick with absolute precision. ROG SpeedNova Wireless Technology delivers low-latency, reliable wireless performance and an optimized power solution in the 2.4 GHz RF mode. The ROG Micro Switch has a 70-million-click lifespan. To minimize switch force deviation between the left and right mouse buttons, switches with gram-force deviation within the +/-5 (g) range are sorted together to ensure a consistent click feel.
