Higher Hump, Narrower Waist Elevated rear hump and a more slender waist in contrast to the standard X2 model. This configuration offers improved stability for those who adopt a more aggressive claw grip, as well as enhanced support for the palm when it's resting on the mouse. If you found the initial X2's height inadequate and desired better palm support, the X2H addresses these concerns effectively. HIGH HUMP DESIGN Enhanced support for the palm INDIRECT WHEEL CLICKS New cutting-edge design incorporates high-quality precision ball bearings, providing smoother rotations without any rattling. Optical switch SPEED OF LIGHT, OPTICAL SWITCH Optical switches avoid double-clicking issues because they don't have physical contacts prone to wear and bouncing, unlike mechanical switches. They use light-based detection, making unintended double clicks less likely. They are also fast due to this light-based detection mechanism, offering quick and precise responses. NO LAG, NO DELAY, LOW POWER 2.4Ghz WIRELESS / WIRED TECHNOLOGY You can either use it wirelessly or wired without the lag. Using the latest MCU and algorithm, it provides wire-free, consistent connectivity with a stable 1ms report rate. 70 hours battery life. Ultra-light Weight 52g You will “wow” when you first hold the X2H mouse. Its super solid built and extremely lightweight. Pulsar Blue Encoder Pulsar Blue Encoder, a recent breakthrough resulting from a successful collaboration with our trusted encoder manufacturing partner. This encoder is designed to provide users with a delightful tactile rotation sensation, all while operating quietly and smoothly. Moreover, its built-in dust-proof mechanism ensures a higher level of reliability by minimizing the risk of potential faults caused by micro dust particles. The most efficient and poweful sensor The latest flagship PixArt's PAW3395 sensor. With its impressive capabilities, including high performance at 26000 dpi, 650 CPI, and 50G acceleration, it is optimized to deliver a top-notch competitive gaming experience. The main chip processor has been upgraded to the industry's leading Nordic MCU, providing exceptional power efficiency and precise, fast processing. As a result, the battery life is extended, and the battery reading is now highly accurate, ensuring you can enjoy extended gaming sessions without worry. Recommeded for Claw, Palm Claw Grip Ultra-comfortable shape for both relaxed claw and palm claw grip users. FULLY CUSTOMIZE IT YOUR WAY Precisely adjust everything with our Software. Re-assign keys, make macros, adjust debounce time as low as 2ms and more. 4K Polling Ready Experience an enhanced cursor movement with the new Pulsar 4K Wireless Dongle, providing smoother and crisper performance. Particularly valuable for high refresh rate monitors, the high polling rate ensures a more current flow of data, perfectly matching the display's faster frequency. By offering up to 4 times more data reports per second, the delay between the latest report and your monitor's frame rendering is significantly reduced compared to a 1000 Hz polling rate, resulting in a seamless and up-to-date cursor experience.
