GravaStar Mercury M2 pairs a high-end PAW3395 sensor (up to 26,000 DPI) with a lightweight 79 g hollowed chassis, USB‑C charging and triple connectivity (2.4 GHz, Bluetooth, wired). It delivers precise, low-latency tracking and long battery life for a wireless gaming mouse, but its unconventional shape and rougher companion software make it a mixed pick for competitive gamers; mediocre for picky esports users, good for style-focused budget wireless buyers.
Buy if you want precise PAW3395 tracking, triple connectivity and a distinctive lightweight design; avoid if you need a conventional, highly ergonomic shape or polished driver software.
