Lenovo has released the Bellator GM104, a lightweight gaming mouse, in China under its Lecoo sub-brand. It pairs a magnesium alloy frame that keeps the body to roughly 55 grams with the latest PixArt PAW3950 sensor and an 8,000Hz polling rate. Priced from 649 yuan (about 15,000 yen), it aims to deliver the low weight and responsiveness competitive players want at an accessible price.
A magnesium alloy frame for about 55 grams
The defining feature of the Bellator GM104 is its weight. The outer shell uses an aerospace-grade magnesium-aluminum alloy with a hollowed-out exoskeleton structure. This allows the body to come in at roughly 55 grams (with a variance of 5 grams) while maintaining a rigid frame. The reduced weight is intended to lessen the hand and wrist fatigue that builds up during long sessions.
The mouse measures 116.77 by 59.32 by 38.31 mm, giving it a relatively compact footprint that can accommodate a range of grip styles, from claw to palm.
PAW3950 sensor and 0.125-millisecond response
For tracking, the mouse uses PixArt's latest PAW3950 optical sensor. Sensitivity is adjustable from 400 to 30,000 DPI, with a maximum tracking speed of 750 IPS and support for up to 50G of acceleration. The result is a cursor that holds up under rapid movements and can keep pace with fast aiming.
The standout figure is the 8,000Hz polling rate, which works over both the wired USB-C connection and the 2.4GHz wireless link. Polling rate refers to how often the mouse reports its position to the PC; at 8,000Hz, input latency shrinks to 0.125 milliseconds. The design is meant to reduce input delay in competitive play compared with a standard 1,000Hz mouse.
Triple-mode connectivity and over 80 hours of battery
The GM104 supports three connection modes: 2.4GHz wireless, Bluetooth 5.2, and wired USB-C. In Bluetooth mode it can pair with up to three devices and switch between them without re-pairing, which suits users who run a gaming PC alongside a work device. The wired mode lets the mouse charge while still being used normally.
Power comes from a 300mAh lithium battery, which Lenovo rates at more than 80 hours in power-saving mode. Built-in circuit protection and voltage regulation manage the output while preserving battery health. The primary buttons use mechanical switches rated for 100 million clicks.
Summary
The Lecoo Bellator GM104 brings together a roughly 55-gram magnesium alloy frame, the PAW3950 sensor, 8,000Hz polling, and triple-mode connectivity in a competition-minded gaming mouse. Offering a flagship-class sensor and high polling rate for 649 yuan (about 15,000 yen), it looks like a strong option for players who want to try a lightweight mouse affordably. For now it is a China launch, but it is another sign of how heated the lightweight gaming mouse market has become.
