The Endgame Gear OP1 8k v2 is a lightweight wired gaming mouse that continues the Endgame Gear OP1 lineup. It retains the same shape, coating options, and Kailh GX SPDT (single-pole double-throw) switches as the original Endgame Gear OP1 8k. These switches offer multiple performance modes and deliver a measurable travel latency advantage over the mechanical switches found in most gaming mice. Like its predecessor, it features hot-swappable main buttons, a rare feature that lets you customize the click feel to your preference with the purchase of additional switch packs. New for this version is a PAW3950 U+1F95A sensor, a Nuvoton MCU, and a Kailh dustproof scroll wheel encoder.
Our Verdict
The Endgame Gear OP1 8k v2 is adequate for work use, though it isn't designed primarily with productivity in mind. It offers excellent build quality and a comfortable symmetrical shape that's best suited for small- to medium-sized hands. You can reprogram its buttons through the configuration software, but the scroll wheel lacks features like horizontal inputs and free scrolling, and since it's a wired-only model, it doesn't support multi-device pairing.
Excellent build quality.
Wired-only.
Scroll wheel lacks tilt inputs and a free-scrolling mode.
The Endgame Gear OP1 8k v2 is exceptionally well-suited for FPS gaming. It features outstanding build quality and an ultra-lightweight design that makes it easy to move quickly and precisely. Its click latency is extremely low and consistent, and its sensor delivers excellent all-around performance. The symmetrical shape is particularly comfortable for claw or fingertip grips, especially for users with medium or smaller hands.

Popular Mouse Comparisons
The Endgame Gear OP1 8k v2 is a wired gaming mouse that continues Endgame Gear's OP1 lineup. Alongside its XM series mice, the company's recent models rank among the best-performing gaming mice on the market. Just like the original, the Endgame Gear OP1 8k, this new version features Kailh GX switches and a hot-swappable switch design but adds modest internal updates, including a new sensor package, MCU, and a dust-proof encoder designed to mitigate the scroll wheel durability issues reported on earlier models. However, these changes don’t yield measurable performance improvements over the already exceptional OP1 8k.
In raw performance, the OP1 8k v2 matches or slightly exceeds leading wireless flagships like the Logitech G PRO X SUPERLIGHT 2 and the Razer Viper V3 Pro, yet it's significantly cheaper. It’s priced similarly to newer budget wireless options like the MCHOSE L7 Ultra, which also shares a similar shape. For most users, there simply isn't any tangible performance advantage to the OP1 8k v2 over its predecessor. However, you may find it appealing for its higher build quality and the peace of mind that comes with knowing it remains among the highest-performing mice available, rather than for any measurable edge. Its only real drawback is that it’s wired, though the lightweight, flexible cable keeps it from feeling restrictive, so it ultimately comes down to personal preference. Overall, the OP1 8k v2 remains one of the best gaming mice available.

The Endgame Gear OP1 8k v2 is the successor to the Endgame Gear OP1 8k. It shares the same shape and Kailh GX switches and supports the same hot-swappable switch packs sold separately. The v2 introduces a new sensor, MCU, and scroll wheel encoder. These internal updates don't result in any measurable or noticeable performance improvement, but the OP1 8k v2 continues the series' legacy, and both versions remain among the best-performing and highest-quality wired mice available.
The Razer Viper V3 Pro and the Endgame Gear OP1 8k v2 are lightweight, high-performance gaming mice designed for competitive play. The Razer is a wireless model with a comparatively flatter shape that suits a wide range of hand sizes and grip types. The Endgame Gear, on the other hand, is smaller and lighter, with a much narrower shape that's best suited for medium or smaller hands. It's also a wired-only model and stands out for using SPDT (single-pole double-throw) switches, which allow it to achieve exceptionally low click latency. That said, the measurable performance difference between the two is extremely small and isn't something you'll realistically notice in-game.
The Logitech G PRO X SUPERLIGHT 2 and the Endgame Gear OP1 8k v2 are both premium mice built for competitive gaming. The Logitech is a wireless model with a slightly larger, more accommodating shape that suits a wider range of hand sizes and grip styles. In contrast, the Endgame Gear is a wired mouse with a smaller, narrower body that's best suited for a claw grip with medium-sized hands. It's also lighter and stands out for its use of Kailh GX switches and support for hot-swappable switch packs available separately from Endgame Gear.
The Endgame Gear XM2 8k and the Endgame Gear OP1 8k v2 are both high-end wired mice that deliver outstanding raw performance and use Kailh GX switches with a unique single-pole double-throw design that offers lower latency than standard mechanical switches. The main difference between them is shape: the XM2 is slightly larger and wider, with a fuller back end that provides more palm support, while the OP1 8k v2 is smaller and narrower with a more centered hump. The OP1 8k v2 also supports hot-swappable switch packs sold separately by Endgame Gear, whereas the XM2 8k does not.
