Gaming mouse Endgame Gear OP1W 4K V2 — right-hand, optical 30,000 DPI, RF Wireless + USB Type-A, 7 buttons, grey

The Endgame Gear OP1w 4k v2 is a right-hand wireless gaming mouse built for competitive play, featuring a custom PixArt PAW3950 U+1F95A optical sensor with up to 30,000 CPI, up to 750 IPS and 50G acceleration. It uses a Nordic nRF52840 wireless MCU in the mouse and a 4k dongle (nRF52820 + Nuvoton M483) to support an ultra-fast wireless polling rate up to 4000Hz. The mouse has a redesigned shape optimized for claw grip, seven buttons including a scroll wheel, swappable main-button switches, a Kailh dustproof encoder, hybrid skate sets, and an estimated battery life of about 30 hours at 4000Hz with default power-saving settings.

Advantages

The OP1w 4k v2 delivers industry-leading click and motion latency through a combination of a high-performance sensor, a Nordic wireless MCU, and a 4k dongle that supports high-speed USB. Mechanical Kailh GX SPDT switches provide crisp, consistent clicks with options for GX Speed or GX Safe modes, while hot-swappable main switches allow easy customization without soldering. The mouse offers advanced tracking options such as an optional locked 20,500 fps sensor frame rate and Sensor Angle Tuning (-127 to +127 degrees) for improved tracking with varied grip styles. A hybrid skate design and an included set of larger skates and sensor skate enable adjustment of glide characteristics to match different surfaces and pads.

Suitable for

• Competitive FPS and esports where low click and motion latency matter
• Players who prefer claw or finger grip styles
• Users who want a highly customizable click feel via swappable switches
• Gamers using RF wireless with a USB Type-A receiver

How to use

Connect the included 4k USB Type-A dongle to your computer and power on the mouse to establish an RF wireless connection. Use the mouse normally with its preinstalled settings; adjust CPI, polling rate and power-saving options via the supported configuration tool or on-device controls if available. To change the main button switches, remove the screws on the bottom plate to open the mouse, swap switches using the universal switch pack or compatible mechanical switches, then reassemble. Replace skates using the included larger or smaller skate sets to tune glide for your mousepad surface.

Recommendations

For optimal performance, keep the dongle unobstructed and use the mouse on a low-friction pad; enable power-saving settings only if you need extended battery life, and consider GX Speed Mode for the lowest click latency during competitive play.
