This article covers エンドゲームギア(Endgame Gear) XM1r ゲーミングマウス PAW3370センサー 50-19.

Overview

The Endgame Gear XM1r is a symmetric gaming mouse that combines a lightweight chassis with a high-performance PixArt PAW3370 optical sensor. Weighing just 70g (without cable), it is built for speed and precision. The mouse uses hand-selected Kailh GM 8.0 switches rated for 80 million clicks, offering a crisp tactile feel with excellent durability. As a refresh of the original XM1, the XM1r improves the sensor, switches, and cable. The PAW3370 sensor delivers up to 19,000 CPI with a 1000Hz polling rate and under 1ms response time. The Dark Reflex coating provides a comfortable, non-slip grip surface.

Connectivity & Compatibility

The XM1r connects via a wired USB interface (USB-A to micro-USB cable). It is plug-and-play on Windows, macOS, and Linux. The included software allows full button remapping, separate X/Y CPI adjustment, ripple control, and angle snapping toggles. No additional drivers are required for basic operation. Compatibility is broad – any device with a USB port will work, making it suitable for desktop PCs, laptops, and even some consoles (if they support USB mice).

Product Info

Released in 2021, the XM1r is still widely available through major retailers like . Pricing typically lands around ¥4,980 (~$35 USD), placing it firmly in the budget-to-mid-range segment for gaming mice. The box includes only the mouse and a quick-start guide – no extra weights or accessories. Warranty is 2 years from the manufacturer (check retailer for details). Market positioning: this is a value-oriented high-performance mouse for competitive gamers. It undercuts many rivals on weight and sensor quality while maintaining build quality.

Best Use Cases

First and foremost, the XM1r excels in first-person shooters and battle royale games. Its light weight allows rapid flick shots and tracking without fatigue. The PAW3370 sensor provides accurate tracking even during fast movements, making it a strong choice for aim-intensive titles. Second, it suits gamers who prefer a claw or fingertip grip. The symmetric shape is designed for these grip styles, offering excellent control and maneuverability. Users with large hands may find palm grip uncomfortable, but medium-to-small hand users will appreciate the fit. Third, the XM1r is ideal for users who want to customize every aspect of their mouse. The software offers granular CPI tuning, button remapping, and sensor behavior adjustments – features often reserved for more expensive models. ## Alternatives
In the same price range, the ZOWIE FK series and the Razer Viper Mini are direct competitors. The XM1r is lighter (70g vs ~85g for Razer) and uses a higher-end sensor than the Viper Mini's PAW3359. The ZOWIE FK uses a 3360 sensor with fewer CPI adjustment steps. The XM1r's software flexibility and lower weight give it an edge for tinkerers and speed-oriented players. However, ZOWIE has a proven track record in esports, and the FK shape may appeal more to palm grippers. Ultimately, grip style preference often determines the winner here.

Things to Consider

The XM1r is wired-only – if you insist on wireless freedom, look elsewhere. The cable is lightweight and flexible but still tethered. Also, the side buttons are positioned only on the left side, making it unsuitable for left-handed users despite the symmetric shape. The mouse is optimized for claw and fingertip grips; palm grippers may find the hump too low. Ensure your hand size and grip match before purchasing.
