The Endgame Gear XM1r is a wired, ultralightweight gaming mouse and an update to the Endgame Gear XM1. The two mice share a very similar symmetrical shape that narrows in the middle and widens in the back. It has a solid, translucent plastic body, it's lightweight, and feels very well-built without any loose or rattling parts. Performance-wise, it has very low click latency, an extremely wide CPI range in which you can precisely set your preferred CPI sensitivity, and a lower lift-off distance than its predecessor.
Our Verdict
The Endgame Gear XM1r is acceptable for office use. It has a sturdy-feeling build quality and a symmetrical shape suitable for most hand sizes. Unfortunately, it doesn't connect wirelessly. Also, the mouse wheel lacks L/R tilt buttons, and you can't unlock it for free scrolling.
- Excellent, solid-feeling build quality.
- Comfortable, ambidextrous design.
- Comfortable and very well-built design.
- Too bulky to slip into laptop cases.
- Wired-only.
- Glossy plastic body shows fingerprints very easily.
The Endgame Gear XM1r is an excellent mouse for FPS gaming. It's lightweight and feels very well-built. It also has very low click latency, a very low lift-off distance, and an extremely wide CPI range in which you can precisely set your CPI sensitivity. The cable and mouse feet are also outstanding, and both slide easily across mousepads and desks. Its shape is well-suited to all grip types, but if you have small hands, you'll have trouble reaching the side buttons if you're using anything other than a palm grip.

The Endgame Gear XM1r is decent for MMO use, but it doesn't have nearly as many side buttons as a dedicated MMO gaming mouse. That said, it's lightweight and feels very sturdy. Its symmetrical shape is well-suited to all grip types and most hand sizes. However, its body widens considerably in the back, meaning if you have small hands, you'll have trouble reaching both side buttons unless you're using a palm grip.

The Endgame Gear XM1r is an update of the Endgame Gear XM1. They're both wired, ultra-light gaming mice with excellent build quality and nearly identical symmetrical shapes, but the XM1r includes several improvements, including better click latency and a lower minimum lift-off distance. Despite having a higher advertised CPI range of 19000, however, The XM1r's current CPI is limited to four onboard presets because it has no companion software. Endgame Gear states it plans to release software in the future, and we'll update the review once it does.
The Logitech G PRO X SUPERLIGHT and the Endgame Gear XM1r are similar gaming mice with symmetrical shapes and comparable performance. The Logitech connects either wired with its charging cable or wirelessly with a USB receiver. It’s also lighter and has a somewhat wider CPI range. On the other hand, the Endgame Gear is a wired-only mouse with marginally lower click latency.
The Endgame Gear XM1r and the Endgame Gear XM2 8k are wired gaming mice with the same shape from the same lineup. The XM1r is an older model while the XM2 8k is a newer model with significantly better raw performance thanks to a new sensor model and support for a higher maximum polling rate of 8000Hz. it also uses Kailh GX mechanical switches, which are SPDT switches that have lower latency click performance settings that the conventional Kailh GM 8.0 switches on the XM1r lack.
The Endgame Gear XM1r is a precursor to the wireless Endgame Gear XM2we. The two mice have identical shapes and share the same sensor, but the XM1r is a wired-only model with lower click latency. It's also available in several different coating options, while the XM2we is not. On the other hand, the XM2we is a wireless model that's slightly lighter. It also has optical switches that are typically more durable compared to the mechanical switches used by the XM1r.
