Verdict

The GravaStar Mercury X is an ultra-lightweight 49g gaming mouse distinguished by its hollow skeleton magnesium alloy frame and unique alien-inspired aesthetic. It features a high-performance PixArt PAW 3950 sensor with a maximum sensitivity of 32,000 DPI and a 750 IPS tracking speed, supporting an 8,000Hz (8K) polling rate for ultra-low latency. The mouse offers tri-mode connectivity (2.4GHz, Bluetooth 5.1, and USB-C wired), five programmable buttons, and GLOWSYNC RGB lighting with six distinct modes. Key pros include its exceptionally durable yet airy build that keeps the hand cool, its precision sensor, and the convenience of web-based configuration software that requires no downloads. However, cons include the lack of onboard storage for the 2.4GHz dongle, web software that can be slow or buggy at times, and a hollow design that may feel uncomfortable for users who prefer a standard palm grip.
