Lenovo’s Lightweight Bellator Duo in a Nutshell
Lenovo’s Bellator GM104 and GM103 are ultra lightweight gaming mouse options that combine high-end optical sensors, tri‑mode connectivity, and 8,000Hz polling to appeal to both competitive and casual players. The Bellator GM104 is a 55g gaming mouse built around the PAW3950 sensor and a magnesium‑alloy exoskeleton, aimed at users who want maximum performance and minimum weight, while the 59g Bellator GM103 relies on the proven PAW3395 sensor and a larger shell to deliver strong value as a more affordable all‑rounder. In short, GM104 suits players chasing every last millisecond and gram, whereas GM103 balances cost, comfort, and features for broader use.
Design, Weight and Comfort: 55g vs 59g in the Hand
The Bellator GM104 goes all‑in on being a 55g gaming mouse by using a hollowed‑out exoskeleton made from aerospace‑grade magnesium‑aluminum alloy. This ultra lightweight mouse still keeps a rigid frame and compact footprint at 116.77 × 59.32 × 38.31 mm, making it suitable for mixed grip styles and fast wrist flicks. The GM103, meanwhile, sits at 59 grams with a 5‑gram variance and follows the wider market trend toward lightweight mice that reduce wrist strain during long sessions. Its larger 128 × 67 × 39 mm body is designed for palm, claw, and fingertip grips, with ergonomics tuned for smaller hands. The practical takeaway: GM104 favors players who want the lightest, tighter‑feeling shell, while GM103 offers more length and width, which many find steadier and more comfortable for everyday use.

Sensor Performance and Connectivity: PAW3950 vs PAW3395
Both mice qualify as high-performance, lightweight gaming mouse options, but their sensors create clear tiers. The GM104’s PAW3950 optical sensor supports 400–30,000 DPI, up to 750 IPS tracking speed, and 50G acceleration. The GM103’s PAW3395 sensor, a widely used and reliable gaming sensor, reaches 26,000 DPI, 650 IPS, and the same 50G acceleration. One quotable detail is that “the GM104’s 8,000Hz polling rate translates to an input latency of 0.125 milliseconds” over both wired USB‑C and 2.4GHz wireless. The GM103 matches that 8,000Hz polling rate in its wired and 2.4GHz modes as well. Both also provide tri‑mode connectivity with Bluetooth 5.2, though GM104 can toggle among three devices while GM103 pairs with two. For sensor headroom and multi‑device flexibility, GM104 pulls ahead; for solid performance with simpler demands, GM103 is sufficient.
Battery Life, Durability and Value for Different Gamers
Longevity is another dividing line. The GM104 uses a 300mAh battery and is rated for over 80 hours in power‑saving mode, while the GM103 doubles capacity to 600mAh and stretches to over 150 hours in its own power‑saving mode. On the click side, GM104’s primary buttons are rated for 100 million clicks, compared with 80 million for GM103. Pricing makes the split obvious: GM104 launches at 649 yuan, roughly USD 95 (approx. RM445), positioning it as a premium ultra lightweight mouse, whereas GM103’s 249 yuan tag, about USD 36 (approx. RM169), plants it firmly in budget‑friendly territory. As a result, GM104 makes more sense for players who treat their mouse as a competitive tool, while GM103 offers strong price‑to‑performance for general gaming and everyday PC work.
Buy if / Skip if
- Buy the Bellator GM104 if you want the lightest possible, 55g ultra lightweight mouse with the PAW3950 sensor and maximum DPI and IPS headroom for competitive play.
- Skip the Bellator GM104 if battery life and budget matter more than shaving 4 grams off your mouse or gaining extra DPI range.
- Buy the Bellator GM103 if you need a lightweight gaming mouse with the PAW3395 sensor, long 600mAh battery life, and a far lower asking price.
- Skip the Bellator GM103 if you prefer a shorter, more compact shell or want the higher‑rated 100‑million‑click switches of the GM104.
- Buy the Bellator GM104 if you often switch among three devices and want magnesium‑alloy construction that prioritizes rigidity and minimal weight.
- Skip the Bellator GM104 if your gaming is mostly casual and the GM103’s 8,000Hz polling, 26,000 DPI, and larger shape already meet your needs at lower cost.
