GravaStar Mercury M2 Wireless Gaming Mouse - Lightweight 26,000 DPI

In this review of the GravaStar Mercury M2, the bottom line is clear: this mouse suits gamers who prioritize ultrafast responsiveness and a lightweight, ventilated shell. The M2 pairs a PAW3395 optical sensor and a 1K Hz polling rate with a hollowed-out chassis that keeps hands cooler during long sessions, and the TUROSPEED wireless options mean there is minimal compromise between speed and convenience. For competitive players who want precise tracking up to 26,000 DPI and customizable controls, the M2 delivers a focused, modern experience.

Key Features

• 26,000 DPI PAW3395 sensor: Delivers high-precision tracking so small hand movements translate to accurate in-game actions at any sensitivity.
• 1K Hz polling rate: Ensures sharp input responsiveness and consistent performance for fast-paced gaming situations.
• Lightweight hollowed-out design: Reduces overall weight to 79g and improves airflow, helping keep grip comfort during extended play.
• TUROSPEED wireless and wired modes: Offers 2.4G wireless, Bluetooth, and wired connection options so users can choose low-latency or power-saving modes.
• 5 programmable buttons: Lets players assign macros and custom functions for faster execution of commands and personalized control layouts.
• GLOWSYNC RGB with five modes: Customizable lighting profiles allow users to match the mouse to their setup and choose reactive or steady effects.

Who It's For

The M2 is well suited for competitive and casual PC gamers who value responsiveness, a high-performance sensor, and a lightweight feel; those who prefer a ventilated, modern aesthetic will also appreciate the hollowed shell. It also works for streamers and desktop builders who want a distinctive, cyberpunk-inspired peripheral with customizable RGB.

Gamers with very large hands or those who prefer a heavy, palm-resting mouse may want to try the fit before committing, as comfort feedback is mixed and some users report it is not ideal for big hands. If silence or a full, solid chassis is a priority, other designs may be a better match.
