Verdict

The Gravastar Mercury M2 is a visually striking, lightweight (79g) gaming mouse defined by its unique hollowed-out skeletal chassis and five-mode GLOWSYNC RGB lighting. It is equipped with a high-end PixArt PAW3395 optical sensor offering up to 26,000 DPI, 650 IPS tracking speed, and 50G acceleration, alongside a standard 1,000Hz polling rate. Its main pros include versatile tri-mode connectivity (2.4GHz, Bluetooth 5.1, and USB-C wired), five programmable buttons, and an impressive battery life of up to 82 hours on Bluetooth or 50 hours on 2.4GHz with lights active. However, common cons include its narrower profile and top-heavy weight distribution, which may be uncomfortable for palm grip users or those with larger hands, and a scroll wheel that some users find lacks sufficient tactile feedback for precise gaming.
