The massive 500mAh battery delivers up to 120 hours at 1000Hz polling - that's literally weeks of gaming between charges. The symmetrical right-handed design accommodates palm, claw, and fingertip grip styles, while the unique ICEFLOW Glacier Coating provides premium texture that stays comfortable during marathon sessions. Premium Omron optical switches deliver lightning-fast actuation with consistent clicking, and the TTC Gold wheel encoder keeps scrolling smooth and precise. PTFE feet ensure buttery gliding, and you get adjustable lift-off distance (0.7mm, 1mm, or 2mm). Available in Black, White, or Rose Red with both web and app driver support, the A7X Ultra is perfect for competitive gamers who want premium materials and flagship 8K performance.
