Endgame Gear OP1

Name: Endgame Gear OP1
Brand: Endgame Gear
SKU: 3426

Manufacturer: Endgame Gear

The Endgame Gear OP1 is a wired gaming mouse built around an ambidextrous form factor, making it accessible to both left- and right-handed users without any ergonomic compromise. It connects via USB with a 1.8 m cable and keeps things straightforward in terms of aesthetics — there is no RGB lighting or decorative weight system, with the design focused squarely on function. At 50.5 g, it sits in a lightweight category that many users targeting low-fatigue extended sessions will find appealing.

At the core of the OP1 is the PixArt PAW3395 sensor, which supports a DPI range spanning from 50 to 26000, with adjustable DPI and a dedicated switching button for on-the-fly adjustments. The mouse reaches a maximum tracking speed of 650 IPS and handles up to 50G of acceleration, while the polling rate runs at 1000 Hz. It offers 6 buttons in total, all of which are programmable, including 2 side buttons, though there is no profile switching button and no onboard memory profiles are stored on the device. The scroll wheel is a standard single-axis unit with no tilt or thumb-scroll functionality.

Pros

At 50.5 g, the mouse is notably light, which reduces hand and wrist fatigue during long sessions
The ambidextrous shape accommodates both left- and right-handed users without requiring a separate variant
All 6 buttons are fully programmable, giving users complete flexibility over the entire input layout
A wide DPI range from 50 to 26000 allows precise tuning across very different sensitivity preferences
The 1.8 m cable provides generous reach without needing an extension for most desk setups
A 2-year warranty offers a solid coverage period for a wired gaming peripheral

Cons

No onboard memory profiles means settings cannot be stored on the device itself and must be managed through software or reapplied when switching systems
The absence of a profile switching button further limits on-the-fly configuration changes without software access
There is no RGB lighting for users who prefer visual customization on their peripherals
The scroll wheel lacks tilt functionality, limiting horizontal scrolling without remapping a button
No extra weights are included, so users who prefer a heavier mouse have no built-in option to adjust the feel

Who is this for?

The Endgame Gear OP1 is well suited to users who prioritize a lightweight, no-frills gaming mouse focused purely on tracking performance. Its ambidextrous shape makes it a practical choice for left-handed users who often find the selection of purpose-built options limited, and the full 6-button programmable layout gives users enough input flexibility for most gaming genres without unnecessary complexity. Those who prefer a clean, minimal desk aesthetic will also appreciate the absence of RGB lighting and the straightforward wired setup with a generously long 1.8 m cable.

Who is this NOT for?

Users who frequently switch between multiple systems or configurations will find the lack of onboard memory profiles a meaningful limitation, as settings cannot be carried with the device. Those who rely on on-device profile switching during a session will similarly be constrained, since no profile switching button is present. Additionally, users who want to fine-tune the physical feel of their mouse through adjustable weights, or who prefer horizontal scrolling via a tilting scroll wheel, will find those options entirely absent from this model.

The Endgame Gear OP1 uses an ambidextrous shape, measuring 118.2 mm in length, 60.5 mm in width, and 37.2 mm in thickness, with a total volume of 266.02 cm³ — a compact footprint that suits a range of hand sizes and grip styles on either hand. At 50.5 g, the mouse is on the lighter end of the spectrum, and no additional weights are included to modify that figure. It ships with a 1.8 m cable and carries no RGB lighting, keeping the aesthetic minimal. The scroll wheel is a standard single-axis unit, with neither tilt nor thumb-scroll functionality present.

Final Verdict

The Endgame Gear OP1 is a wired gaming mouse that makes a clear statement about its priorities — tracking precision and a lightweight, ambidextrous build over feature density. Its 50.5 g body paired with the PixArt PAW3395 sensor and a fully programmable 6-button layout form a coherent package aimed at users who want capable, distraction-free performance at their fingertips. The trade-offs — no onboard profiles, no adjustable weight system, and no profile switching button — are consistent with a design philosophy that strips away complexity rather than adding it. For gamers who value a clean, responsive wired mouse without the overhead of onboard customization hardware, the OP1 makes a well-reasoned case for itself.
