The OP1w 4k wireless gaming mouse with a Nordic Wireless MCU delivers a wireless polling rate of 4,000 Hz for extremely low latency during clicks and movements. The precise PixArt PAW3395 sensor and the exclusive Kailh GX switches ensure crisp, precise clicks. Thanks to interchangeable main button switches, you can customise the click feel - perfectly tailored to your playing style. So that you can enjoy the best possible performance, the OP1w 4k relies on a powerful Nordic nRF52840 wireless MCU. The included 4k dongle also uses a Nordic nRF52820 MCU to ensure stable and reliable wireless data transmission. In addition, a Nuvoton M483 MCU is used, which is responsible for the high-speed USB connection. The result? Wireless sampling rates of up to 4,000 Hz, giving you incredibly low sensor and click latency. Best of all, the 4k dongle is already included with the mouse so you can enjoy full performance right out of the box. The Kailh GX switches developed by Engame Gear ensure that you never miss an important click - regardless of the sampling rate. Thanks to their SPDT configuration, they offer optimal electrical contact and unrivalled reliability. The switches are designed to have both top and bottom contacts, giving you the choice between the ultra-fast GX Speed mode or the safe GX Safe mode. What really sets the Kailh GX Switches apart is their crisp, precise click feel that gives you tactile feedback for better in-game control. The precise actuation and balanced design make them perfect for fast click series - ideal for intense matches where every millisecond counts. The OP1w 4k sets the benchmark in wireless performance, achieving an average click latency of less than 310 microseconds. With a stable click sampling rate of 4,000 Hz, you can enjoy low latency times, regardless of the selected sensor sampling rate. In GX Speed mode, you can even reduce the click latency by a further 1 ms.
