Raw Performance

The Endgame Gear OP1we is a lightweight wireless gaming mouse. It has a symmetrical shape and a low hump positioned towards the back of the mouse that's identical to the other mice in Endgame Gear's OP1 lineup. Endgame Gear positions this mouse and other "wireless essentials" (we) models in the upper mid-range category since it uses the PixArt 3370 sensor, which is the best of the previous generation of sensors. It also uses Kailh GO optical switches, which you can easily hot-swap for an alternate set of Kailh optical switches.

Our Verdict

7.2 Work

The Endgame Gear OP1we is decent for work despite not being specifically designed for it. It has excellent build quality with a comfortable symmetrical shape, and you can remap its buttons using the companion software. It connects wirelessly with its USB receiver but doesn't support Bluetooth or multi-device pairing. Also, its scroll wheel has no additional functionality like free scrolling or L/R tilt inputs.

  • Excellent build quality.
  • Small shape is unsuitable for large hand sizes.
  • No Bluetooth connectivity or multi-device pairing.
  • Scroll wheel lacks free-scrolling and L/R tilt inputs.
8.8 Video Games (FPS)

The Endgame Gear OP1we is an excellent mouse for FPS gaming. It's very lightweight, making it easy to move quickly and accurately, and its small, symmetrical shape is ideal for claw or fingertip grip types. It also delivers remarkable raw performance with excellent click latency and sensor latency, providing a responsive gaming experience.

  • Excellent click latency.
  • Amazing sensor latency.
  • Very lightweight.
  • Excellent build quality.
  • Small shape is unsuitable for large hand sizes.
  • 1000Hz polling rate is no longer cutting edge.
7.7 Video Games (MMO)

The Endgame Gear OP1we is a good mouse for MMO gaming, but it doesn't have nearly as many side buttons as a dedicated MMO mouse. That said, you can still program almost all of its buttons using the companion software, and it has excellent build quality and raw sensor performance.

  • Excellent click latency.
  • Amazing sensor latency.
  • Excellent build quality.
  • Small shape is unsuitable for large hand sizes.
  • 1000Hz polling rate is no longer cutting edge.
  • Significantly fewer side buttons compared to dedicated MMO mice.
9.1 Raw Performance

The Endgame Gear OP1we has remarkable raw performance. Despite using the older PixArt 3370 sensor, it delivers excellent click and sensor latency, providing an accurate and consistent gaming experience. That said, its maximum polling rate is 1000Hz, which doesn't detract from the experience but falls short of some of the competition offering higher polling rates.

  • Excellent click latency.
  • Amazing sensor latency.
  • 1000Hz polling rate is no longer cutting edge.
  • 7.2 Work
  • 8.8 Video Games (FPS)
  • 7.7 Video Games (MMO)
  • 9.1 Raw Performance

Differences Between Sizes And Variants

The Endgame Gear OP1we is available in black or white. We bought and tested it in white. You can see the label of our unit here.

Compared To Other Mice

The Endgame Gear OP1we is a lightweight wireless gaming mouse with a symmetrical shape. It shares its shape with other mice in Endgame Gear's OP1 lineup, like the OP1, the OP1 8K, and the OP1 RGB. It's on the smaller side and is designed for fingertip and claw grip types. It's only really suitable for a palm grip if you have small hands. It uses the PixArt PAW3370 sensor, which, while excellent-performing, only supports a maximum polling rate of 1000Hz, whereas the newer PixArt PAW3395 sensor found in mice like the LAMZU Atlantis Mini 4K, Pulsar X2V2, and Endgame Gear OP1 8k supports higher polling rates. This mouse also offers the unique advantage of having easily hot-swappable optical switches. Endgame Gear even sells lighter replacement switches on its website here. Overall, this mouse is a fantastic choice if you're looking for a high-performance gaming mouse that stands out for its smaller shape and excellent build quality.

For more options, see our recommendations for the best gaming mouse, the best wireless gaming mouse, and the best claw grip mouse.

Endgame Gear OP1 8k

The Endgame Gear OP1 8k and the Endgame Gear OP1we are gaming mice that share the same shape and belong to the same wider product lineup. The OP1 8k is a wired-only model that's more geared towards enthusiasts. It offers significantly better click latency and sensor latency. It's also lighter and has a higher maximum polling rate of 8000Hz. It also uses mechanical SPDT switches. The OP1we, on the other hand, is a wireless model. It still offers superb raw performance but doesn't quite match that of the OP1we. It uses optical switches and has a lower maximum polling rate of 1000Hz.

Endgame Gear XM2we

The Endgame Gear OP1we and the Endgame Gear XM2we are lightweight wireless gaming mice. They have symmetrical shapes with similarly excellent build quality and grippy matte finish. While their overall shapes are similar, the XM2we is significantly larger than the OP1we, making it a better fit if you have large hands. Performance-wise, the two mice are similar. They have the same PixArt 3370 sensor, but the XM2we's raw performance is better.

Endgame Gear XM1r

The Endgame Gear OP1we and the Endgame Gear XM1r are symmetrical high-performance gaming mice. The OP1we offers wireless connectivity, whereas the XM1r is wired-only. Their shapes are slightly different, too, with the OP1we being smaller and much narrower than the XM1r. Both mice have excellent build quality, but the XM1r is available in a variety of different colors and coatings, whereas the OP1we is only available in black or white with a matte coating. Both mice deliver excellent performance, but the XM1r has lower latency and a more accurate sensor.


The Endgame Gear OP1we and the Logitech G PRO X SUPERLIGHT 2 are lightweight wireless gaming mice with symmetrical shapes. The Endgame Gear is smaller and has a hump that's closer to the back of the mouse, making it well-suited for fingertip and claw grip types. The Logitech has a well-rounded shape that's suitable for a wide range of hand sizes and grip types. Both mice deliver excellent performance, but the Logitech has better click latency and a maximum polling rate of 4000Hz, whereas the endgame gear has a maximum polling rate of only 1000Hz.

Razer Viper V2 Pro

The Endgame Gear OP1we and the Razer Viper V2 Pro are lightweight wireless gaming mice with symmetrical shapes. The Endgame Gear is smaller and more explicitly designed for claw grip types, whereas the Razer has a safer shape that's suitable for various grip types and hand sizes. The Razer performs better thanks to its lower click latency and more accurate sensor. It also supports higher polling rates if you buy Razer's HyperPolling dongle, which is sold separately.

This mouse is small and has a low profile shape that makes it easy to bring with you. That said, it lacks an internal compartment to store its USB receiver when it's not in use.

Build Quality

This mouse has excellent build quality. Its solid plastic body has a chalky-feeling "dry grip" coating that feels very high-quality. It's well put together, doesn't creak or rattle during normal use, and doesn't even flex if you press into the body forcefully.

This mouse is designed to be easily opened to change the main click buttons thanks to the exposed screws on the underside of the mouse.

Hand Size Recommendation
Palm Grip Hand Recommendation
Claw Grip Hand Recommendation
Fingertip Grip Hand Recommendation

This mouse has a narrow, symmetrical shape with a low hump towards the back of the body. It has flat sides that widen slightly at the back of the mouse. Its shape accommodates most 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.
