Our Verdict
Keychron M4
G-Wolves Fenrir Max
The Keychron M4 and G-Wolves Fenrir Max are lightweight wireless gaming mice designed exclusively for fingertip grip. The Keychron is much longer and slightly taller, with a more centered hump and a fully enclosed plastic shell. In contrast, the G-Wolves is noticeably smaller and lighter, featuring a closed plastic top shell and an open bottom plate design that leaves it more exposed to dust and debris. The G-Wolves mouse also offers better build quality, higher-quality mouse feet, and better sensor performance.
