Endgame Gear - OP1w 4k: Wireless Polling Rate up to 4,000 Hz

To ensure you get the best performance, the OP1w 4k utilises a powerful Nordic nRF52840 Wireless MCU. The included 4k dongle also uses a Nordic nRF52820 MCU to ensure stable and reliable wireless data transmission.

An additional Nuvoton M483 MCU handles the high-speed USB connection. The result? Wireless polling rates of up to 4,000 Hz, giving you incredibly low sensor and click latency.

And the best part: The 4k dongle is included with the mouse, so you can enjoy its full performance straight out of the box.

Next-Generation Kailh GX Switches

Endgame Gear’s custom Kailh GX switches ensure you won’t miss any critical clicks—no matter the polling rate. Thanks to their SPDT configuration, they provide optimal electrical contact and unmatched reliability. The switches are designed with contacts at both the top and bottom, allowing you to choose between the ultra-fast GX Speed mode or the secure GX Safe mode.

What truly sets the Kailh GX switches apart is their crisp, precise click feel, providing tactile feedback for better in-game control. The precise actuation and balanced design make them perfect for rapid-clicking sequences—ideal for intense matches where every millisecond counts.

Industry-Leading Latency - Your Competitive Edge in the Game

The OP1w 4k sets new standards in wireless performance, achieving an average click latency of less than 310 microseconds. With a stable click polling rate of 4,000 Hz, you enjoy low latency times regardless of the selected sensor polling rate. In GX Speed mode, you can further reduce click latency by an additional 1 ms.

This responsiveness ensures that each of your clicks is registered instantly—perfect for moments where milliseconds decide victory or defeat.

And that’s not all: Movement latency has also been optimised, averaging below 400 microseconds. This means your mouse movements are captured instantly and accurately, without delay, regardless of the polling rate. Stay one step ahead in the game.

Newly Developed Shape - Perfect for Versatile Claw Grip

The OP1w 4k gaming mouse ensures you enjoy full comfort even during long gaming sessions, allowing you to focus entirely on your performance. Based on the popular XM shape, the design has been specifically enhanced to provide claw-grip players with even greater control. Flatter sides offer maximum flexibility for finger placement—ideal for players with larger hands.

The slightly extended side walls prevent accidental clicks, allowing you to rest your fingers on the edges comfortably without triggering unintended actions. This thoughtful design adjustment ensures added comfort and precise control, no matter your hand size or grip technique.

Customisable Switches & Hybrid Skate Design - Tailored Just for You

What makes the perfect mouse click? That’s a matter of personal preference. That’s why the OP1w gaming mouse features interchangeable main switches. The pre-installed Kailh GX switches offer a crisp actuation point and quick response time. However, if you prefer your favourite switch, you can easily swap them out without soldering, thanks to accessible screws on the bottom plate. Find your perfect click feel.

The glide behaviour is also customisable: The OP1w 4k features a clever hybrid skate design. By default, a small skate set provides balanced glide properties. For softer mousepads or maximum glide, we include a larger skate set and a sensor skate. And the best part: You can change the switches without removing the skates, allowing for seamless adjustments to suit your preferences.
