The XM1r is a refresh of the popular XM1 series of gaming mice and the latest innovation from Endgame Gear. The XM1r offers user-requested features and improvements and is engineered for maximum performance to ensure an utmost accurate and responsive gaming experience.

Updates include the PixArt PAW3370 optical sensor custom-sorted Kailh GM 8.0 main button switches new side button and middle mouse button switches a hybrid skate design and completely re-written and performance-optimized firmware and software developed in Germany.

The Dark Reflex variant has a dark semi-transparent shell and a glossy finish.

The Endgame Gear XM1r at a glance:

• New Pixart PAW3370 up to 19000 CPI
• Kailh GM 8.0 switches
• Updated more durable flex cord
• Two new dark semi-transparent colours and two classic colours
• Hybrid skate design - large and small skates included

Advanced sensor - enhanced sensitivity

The highlight of this refresh is undoubtedly the XM1r’s responsiveness. It utilises the latest Pixart PAW3370 sensor with the XM1r being one of the first gaming mice to use it. The sensor is fine-tuned for maximum performance which means users can expect low input lag no smoothing and no power-saving states.

This sensor has a resolution of 50-19000 CPI and the CPI can be adjusted in increments of 50 CPI from 50 to 10000 CPI and in increments of 100 CPI from 10000 to 19000 CPI. Every effort has been made to squeeze the last ounce of performance from this sensor. With no smoothing averaging or interpolating the tracking data from the sensor is as raw as it can be.

Additional specifications which will appeal to esports professionals include a tracking speed of 400 IPS polling rates of 125 500 and 1000 Hz (1000Hz by default) and a lift off distance of 1mm (2mm via software).

Innovative switches and technology

The team at Endgame Gear have not only updated the optical sensor but added improved switches to the XM1r. This update uses Kailh GM 8.0 in the right and left buttons. Standard Kailh GM 8.0 switches have an actuation force of 65+-10gf with the range being 55-75gf. The custom-sorted GM8.0 in the XM1r have a super narrow operating force range of 55-60gf which results in a pleasant light and crucially accurate click.

Meanwhile the side button TTC micro switches have been updated for a crisper and more consistent click feel as well as added durability.

The XM1r retains the popular tactile Japanese ALPS wheel encoder being used in the original XM1 from day one. This gives the wheel scroll steps a distinctive yet accurate feeling.

The XM1r still utilizes an STM32 ARM microcontroller and features its patented analogue technology which enables click response times of below 1ms superior to traditional digital approaches which for mechanical switches are usually in the range of 2ms to 10ms.

New colours same great design

The XM1r is available in two new colours in addition to the classic black and white. This Dark Reflex option has a dark semi-transparent shell and glossy finish. The result is an eye-catching aesthetic with the circuit board inside the XM1r visible.

Other design enhancements include an adjustment to the Endgame Gear logo which now appears as a solid colour to complement the Dark Reflex’s finish.

Endgame Gear has retained the established XM1 shape so the XM1r is perfect for claw grips. However they have updated the flex cord for improved durability while retaining its flexibility - in fact it almost feels like using a wireless mouse.

Hybrid skate design for scrolling customisation

Additionally Endgame Gear has responded to feedback and now include both large and small skates with the XM1r. While the small skates are fitted by default by way of a well-engineered hybrid design it is possible to easily install the large skates. This gives users yet further customisation options when it comes to how smooth the mouse scrolls and ensures you don’t have to risk buying low-quality third party options.

New software

A highlight of the XM1r will surely be its new redesigned software which allows for more personalisation of settings than the previous version. From bindable scroll as well as assignable multimedia keys. Additionally individual x/y CPI settings can be adjusted instead of users only being able to change single values. Ripple control and sensor angle snapping have been included. Plus the software can be set to auto-update both itself and the firmware.
