The G-Wolves Fenrir Pro enters the competitive gaming mouse market as one of the lightest options available at just 20 g. This Chinese peripheral maker's latest creation combines elements from its Fenrir Asym and Max predecessors, offering a symmetrical design with optimized mechanical construction that shaves off another gram compared to the Asym model.

Under the hood, the Fenrir Pro packs PixArt's PAW3950 sensor paired with Nordic's latest nRF54L15 MCU for improved battery efficiency. The mouse supports 8000 Hz polling rates in both wired and wireless modes, though it lacks SPDT switches due to space constraints. Instead, it uses Omron D2LS-21 surface-mounted switches already found in the Asym. A web-based driver handles configuration.

At $159, the Fenrir Pro targets enthusiasts seeking maximum performance in the lightest package possible. Available in six colors including black, white, and pink, it competes directly with premium ultra-lightweight offerings from Razer and Finalmouse. The one-year warranty provides basic coverage for the investment.

While the 20g weight appeals to competitive gamers, the lack of wireless charging and SPDT switches may disappoint some users. The high polling rate support makes it future-proof for esports competitors who demand millisecond precision.
