Built for Competitive Play While the outer shape remained identical to the famous XM claw grip shape, the inside was re-designed to achieve a lower overall weight of ~62g while maintining a robust shell design without holes. The XM2w 4k has been developed by esports veterans for use in competitive play, with top-of-the-line components including PixArt's PAW3395 sensor, the Nordic nRF52840 wireless MCU, and Endgame Gear's exclusive Kailh GX SPDT switches with GX Mode compatibility.   Wireless Polling Rate of up to 4000Hz To achieve the best performance possible, XM2w 4k is powered by the Nordic nRF52840 wireless MCU. The 4k dongle utilizes a Nordic nRF52820 to guarantee stable and reliable wireless data transmissions. Additionally, a Nuvoton M483 MCU is used for the high-speed USB connection, enabling high wireless polling rates of up to 4000Hz for incredibly low sensor and click latency. The 4k dongle is included with the mouse for ideal performance straight out of the box.   Kailh GX Switches developed by Endgame Gear Designed for lightning-fast precision at all polling rates, the mechanical Kailh GX switches guarantee you won't miss a crucial click. Their SPDT configuration ensures optimal electrical contact and unmatched reliability. Featuring both top and bottom contacts, Kailh GX Switches excel whether you prefer low click latency in GX Speed Mode or security in GX Safe Mode. What sets them apart is their crisp, defined click sensation, offering tactile feedback for enhanced gaming control. Precise actuation and a balanced design ensure flawless, spam-friendly rapid-fire actions.   Hybrid Skate Design The XM2w 4k comes with two sets of PTFE skates (large & small) and a sensor skate. Thanks to a hybrid design bottom shell, it's possible to easily install either large or small skates with the smaller skates fitted by default. The larger area offers added flexibility when customizing the XM2w 4k's glide and re-using already purchased skates. The sensor skate is optional but recommended on softer surfaces.   (Almost) No Power-Saving Engineered for peak performance the moment you plug it in, XM2w 4k ensures every click and movement is delivered with precision and speed. While the focus is on performance, we’ve also integrated customizable power settings for those who want to extend their battery life. Fine-tune your experience with adjustable sensor power-saving options and customizable deep sleep timers, giving you more control without sacrificing performance.   Tech Specs Mouse Specifications Skates Hybrid Skate DesignSkates note small skates pre-installed, large skates includedMicrocontroller Nordic nRF52840 Standards / Specifications Polling Rate 4000 Hz, 2000 Hz, 1000 HzPolling Rate note 4000Hz by default Ergonomics Mouse layout right-handedSupported Grip Types Claw Grip, Palm Grip, Finger Tip Grip Sensor Sensor Type OpticalSensor Model Pixart PAW 3395DPI adjustable YesMin.
