- Chassis weight of 2.72 oz (77 g) is heavier than modern ultra-lightweight esports competitors.
Overview
Integrating a dedicated magnetic charging dock that functions simultaneously as an active 2.4 GHz RF signal extension pedestal, the hardware establishes a direct line-of-sight wireless transmission pathway to prevent packet drop across desk environments. The mouse itself is built into a symmetrical, ambidextrous shell measuring 4.53 x 2.28 x 1.55 in (115 x 58 x 39.4 mm) with a total mass of 2.72 oz (77 g). Finished in a matte crimson and charcoal thematic scheme inspired by Gears of War: E-Day, the unibody polymer shell avoids weight-reduction perforations, ensuring structural rigidity under heavy palm pressure while integrating magnetic charging contacts flush against the base plate alongside low-friction PTFE glide feet.
Internal tracking is driven by a PixArt PAW3395 optical sensor supporting up to 26,000 DPI, 650 IPS tracking speed, and 50G acceleration. Processing bandwidth accommodates an 8,000 Hz polling rate in wired USB-C mode and up to 4,000 Hz wirelessly over 2.4 GHz, complemented by standard Bluetooth 5.3 LE connectivity for secondary devices. Primary click actuation relies on Kailh Sword GM X micro switches rated for 100 million actuations, providing a distinct mechanical snap with clean acoustic return and contact longevity that mitigates double-clicking degradation over prolonged use cycles.
Power delivery centers on an internal 450 mAh rechargeable lithium-ion cell, replenished in approximately 2.5 hours via the magnetic dock or direct USB-C connection. Battery runtime scales substantially with bus transmission demand: standard 1,000 Hz polling over 2.4 GHz yields up to 105 hours (and up to 100 hours over Bluetooth), whereas pushing the controller to its peak 4,000 Hz wireless polling rate increases transmission cycles and reduces operational endurance to roughly 26 hours. Software configuration and button mapping—including ambidextrous handedness toggling—are handled through the 8BitDo Ultimate Software suite, providing local profile storage without requiring continuous background cloud synchronization.
