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.

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 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.
The MCHOSE L7 Ultra and the Endgame Gear OP1 8k v2 are gaming mice with very similar symmetrical shapes and exceptionally good click and sensor latency performance. The MCHOSE is a wireless model, while the Endgame Gear is a wired-only model. The Endgame is also noteworthy for its Kailh GX switches, which have a unique single-pole double-throw design that produces slightly lower latency. It also has better build quality and supports hot-swappable switch packs sold separately by Endgame Gear.
Test Results
This mouse has a simple, understated design that's consistent with other recent Endgame Gear models. There's a small Endgame Gear logo on the front left side, and while there are no RGB lighting zones, there's a small LED on the underside that displays what CPI you're using.
We tested a Black color version which has a matte opaque finish. There's also a White version with the same finish and a Dark Frost version, which has a translucent grey finish. For more details about the coating differences between these versions, see the Build Quality section.
Because of the slightly reflective quality of this mouse's plastic finish, we applied a spray aerosol that leaves small white flecks to achieve a readable scan. The accuracy of the dimensions represented are unaffected by this process.
The Endgame Gear OP1 8k v2 has excellent build quality. The fit and finish are very good, with smooth seams and high-quality materials that feel solid in hand. There are no rattling sounds, and it feels very sturdy, despite its very light weight. There's a slight amount of flex if you press on the baseplate beneath the sensor, but it doesn't cause any issues during normal use.
The Black version we tested has a dry, chalky coating that offers a good amount of grip but shows fingerprints fairly easily. Endgame Gear notes that both the Black and White versions use this chalky, smooth coating reminiscent of dry stone, while the Dark Frost version features a translucent plastic body with a slightly soft and rubberized feel.
This mouse is designed to be easy to disassemble yourself. It includes a screwdriver in the box, and there are visible screws on the underside that don't require you to remove the mouse feet to access, which is a fairly uncommon feature compared to other mice.
The Endgame Gear OP1 8k v2 shares the exact same shape as its predecessor, the Endgame Gear OP1 8k. It has quite a narrow, symmetrical shape with a low-profile hump towards the back of the body. The sides are fairly flat but widen slightly toward the back. Overall, this shape accommodates all grip types if you have smaller hands, but it's best suited for claw and fingertip grip types. If you have larger hands, you'll likely find it too small for a palm or relaxed claw grip.
The Endgame Gear OP1 8k v2 uses a light, flexible paracord-style cable that moves smoothly across both desks and mousepads. However, it can retain slight permanent bends from its packaging. The cable exits the mouse at a slight upward angle to help reduce drag.
The cable is non-detachable. Endgame Gear previously sold replacement cables for the original Endgame Gear OP1 8k on their website that could be installed after disassembling the mouse, but those cables don't appear to be compatible with the OP1 8k v2.
This mouse has high-quality feet that provide a very smooth glide across mousepads and hard surfaces. It also includes an optional set of larger skates, along with an extra ring that fits around the sensor, which is useful if you prefer a softer pad or tend to press more firmly and need a bit more surface contact.

The Endgame Gear OP1 8k v2 uses Kailh GX SPDT (single-pole double-throw) switches that have both top and bottom contact points. These switches are designed to deliver extremely low latency while also reducing the likelihood of accidental double-clicks.
Through the configuration software, you can toggle between GX Speed, GX Safe, or OFF modes. GX Speed mode offers the fastest possible click response, with detection occurring as the contact plate lifts away from the top contact. In contrast, when SPDT mode is OFF (as with most standard mechanical switches), the click is registered when the contact plate makes contact with the bottom plate.
GX Safe mode is just as fast as the OFF setting but adds extra hardware debounce to guard against potential double-clicking events.
This mouse's main buttons also have a hot-swappable design, allowing you to open your mouse and change or replace switches without soldering. For an additional purchase, you can buy switch packs on Endgame Gear's website. Each switch pack includes a set of two switches that are pre-soldered to a switch PCB. Endgame Gear sells a variety of switch options, including lighter, heavier, and silent switch options.
You can reprogram all buttons on the Endgame Gear OP1 8k v2 using the configuration software except for the left-click button and the 'mode' button, which cycles between CPI settings on the underside.
The Endgame Gear OP1 8k v2 has exceptionally low and consistent click latency, delivering an extremely responsive in-game experience across all genres.
The results above were measured at the maximum polling rate of 8000Hz with the SPDT GX Speed mode enabled. Testing with SPDT GX Safe mode produced the same 0.6 ms result, confirming Endgame Gear's indication that this setting doesn't affect latency performance. Similarly, lowering the polling rate doesn't change click latency, since the mouse only reports click events at 8000Hz. Testing with the Multiclick Filter, both on and off, also has no impact on click latency performance.
When SPDT is turned OFF, latency performance is affected, with a slightly higher average of 1.3 ms, which is expected and consistent with Endgame Gear's indications.
The Endgame Gear OP1 8k v2's sensor consistently tracks your movements exceptionally well with no speed variation or tracking issues.
The Endgame Gear OP1 8k v2 has remarkably good sensor latency. The sensor reacts extremely quickly when you move your mouse, and these movements closely match the timing of the cursor movements you see on-screen.
This test was performed using the maximum polling rate of 8000Hz with Motion Sync off.
We also performed supplementary testing at 1000Hz, 4000Hz, and at 8000Hz with Motion Sync On:
1000Hz:
- Delay to start of movement: 9.3 ms
- Delay at half movement: 1.3 ms
- Delay to end of movement: 1.0 ms
4000Hz:
- Delay to start of movement: 10.1 ms
- Delay at half movement: 1.1 ms
- Delay to end of movement: 0.6 ms
8000Hz, Motion Sync On
- Delay to start of movement: 10.1 ms
- Delay at half movement: 1.1 ms
- Delay to end of movement: 0.7 ms
The available polling rate options are 1000Hz, 2000Hz, 4000Hz, and 8000Hz.
This mouse has a grooved scroll wheel with a grippy rubberized coating. Endgame Gear indicates on their product page that this mouse is using a new dustproof Kailh encoder. This may provide increased reliability over the TTC encoder used in the previous version, the Endgame Gear OP1 8k. Despite moving to a different encoder, scrolling feels similar with very precise and consistent, well-defined steps.
Unlike many larger gaming brands that ship bloated configuration software that consumes significant system resources and needs frequent updates, Endgame Gear's Configuration Tool is a lightweight standalone executable. The software is straightforward and easy to navigate, with all expected settings organized across several tabs.
It also supports several advanced sensor options:
Motion Sync: Synchronizes sensor data with USB polling events, which can make on-screen motion feel more consistent. While enabling it can incur a negligible sensor latency penalty, we recommend trying this setting to see whether you prefer the feel with or without it and using whichever option feels best to you.
Slam-click Filter: Helps prevent unintended inputs if you often lift and reposition your mouse during gameplay.
Glass Mode: Endgame Gear specifies on their Discord that this setting is intended for clear glass surfaces like tables, not glass mousepads. Just note that enabling this mode locks the polling rate to 1000Hz.
Multiclick Filter: According to Endgame Gear, this isn't a pre-debounce slider but instead filters out switch bouncing after the first signal is detected, which they claim can be beneficial as switches begin to degrade. Clicks are always polled at 8000 Hz, so adjusting this slider doesn't change latency but alters the click duration instead. They warn that setting the Multiclick Filter to zero can cause severe multiclicks, which most users will want to avoid unless they're intentionally multiclicking, such as drag clicking or butterfly clicking in competitive Minecraft or other high-CPS scenarios.
You can also adjust SPDT switch settings. For more details about SPDT settings, see the Main Button section above.
