Endgame Gear OP1w 4K V2 Mouse

The Endgame Gear OP1w 4K V2 is a lightweight wireless mouse designed primarily for claw grip users who prioritize precision and low latency in competitive gaming. Its shape suits a range of hand sizes, especially those who prefer a flatter grip style with enhanced finger placement control. This mouse targets gamers seeking high responsiveness and customizable click feel without extra buttons or complex features.

Sensor & Tracking

• Equipped with a PixArt PAW3950 U+1F95A optical sensor, it delivers up to 30,000 CPI for fine-tuned sensitivity adjustments.
• Supports up to 750 IPS and 50G acceleration, capturing fast movements accurately.
• Offers a polling rate up to 4000Hz via the included 4K dongle, reducing input delay for quicker response times.
• Features adjustable lift-off distance in 0.1mm steps, allowing users to optimize tracking for their play style.
• Sensor Angle Tuning lets users align the tracking axis to their grip angle, improving accuracy for angled swipes.

Connectivity & Latency

• Wireless connection uses a Nordic nRF52840 MCU for stable data transmission and a Nuvoton M483 MCU in the dongle for high-speed USB communication.
• Click latency averages below 310 microseconds, with GX Speed Mode further reducing delay by about 1ms.
• Motion latency averages under 400 microseconds, supporting fast and consistent tracking.
• Battery life is approximately 30 hours at 4000Hz polling rate, with customizable power-saving and deep sleep modes.

Shape & Ergonomics

• Inspired by the XM shape but with flatter sides, it supports claw grip users and offers flexibility for larger hands.
• Extended side walls prevent accidental clicks, enabling finger rest without unintended input.
• Lightweight at 59.5g, reducing fatigue during long gaming sessions.

Buttons & Switches

• Main buttons use Kailh GX SPDT switches compatible with GX Mode for low latency clicks.
• Side and middle buttons use Kailh GM 2.0 switches, balancing durability and responsiveness.
• Main button switches are hot-swappable without soldering, allowing users to customize click feel easily.

Build Quality

• Includes two sets of PTFE skates with improved adhesive for smooth, consistent glide.
• Dustproof Kailh encoder enhances durability of the scroll wheel.

Trade-offs

• Lacks additional programmable buttons, which may limit functionality for MMO or productivity users.
• Software customization is focused on performance settings rather than extensive macros or profiles.
• Wireless design prioritizes responsiveness over absolute battery longevity, requiring regular charging for extended use.
