GravaStar Mercury M2

Name: GravaStar Mercury M2
Brand: GravaStar
SKU: 6520

Manufacturer: GravaStar

The GravaStar Mercury M2 is a right-handed wireless gaming mouse built around a tri-mode connection setup, supporting 2.4GHz wireless, USB wired, and Bluetooth 5 simultaneously. At 79 g and with a compact footprint of 120 x 60 x 40 mm, it is designed with portability and extended sessions in mind. RGB lighting is included, and the mouse can be used while charging, making battery depletion less of an interruption during longer gaming sessions.

The M2 is equipped with the PixArt PAW3395 sensor, which supports a DPI range spanning from 100 to 26000, with a maximum tracking speed of 650 IPS and a maximum acceleration of 50G. The polling rate runs at 1000 Hz, and all five buttons are fully programmable, including two dedicated side buttons and a DPI switching button. Battery life is rated at 70 hours on a single charge, and connectivity over Bluetooth 5 broadens its compatibility across devices. There are no onboard memory profiles, no profile switching button, and no tilt scroll wheel or thumb scroll wheel.

Pros

Tri-mode connectivity via 2.4GHz wireless, USB, and Bluetooth 5 offers flexibility across different setups
Battery life rated at 70 hours per charge reduces the frequency of interruptions during extended use
The mouse can be used while charging, so a depleted battery does not force a pause in use
All 5 buttons are fully programmable, including 2 side buttons and a dedicated DPI switching button
A wide DPI range from 100 to 26000 allows precise sensitivity tuning across very different use cases
At 79 g, the mouse is lightweight enough for extended sessions without adding significant physical fatigue

Cons

No onboard memory profiles means settings cannot be stored on the device and recalled across different systems
The battery is not removable, so replacement requires servicing rather than a simple swap
No profile switching button on the mouse itself limits on-the-fly profile changes
Right-handed only orientation excludes left-handed users entirely
No tilting or thumb scroll wheel limits scrolling input options for users who rely on those features

Who is this for?

The GravaStar Mercury M2 is well suited to right-handed gamers who want the flexibility of tri-mode connectivity — switching between 2.4GHz wireless, USB, and Bluetooth 5 depending on their setup. The 70-hour battery life combined with use-while-charging support makes it a practical choice for users who game in long sessions and cannot afford downtime. The broad DPI range from 100 to 26000 and a 1000 Hz polling rate also cater to users who regularly adjust sensitivity settings across different game types, while the lightweight 79 g build suits those who prefer a less fatiguing mouse over extended periods of use.

Who is this NOT for?

Left-handed users are entirely excluded by the right-handed-only design, making this mouse unsuitable for that group regardless of other preferences. Users who rely on onboard memory profiles to carry their settings between different machines will find the lack of any profile storage a meaningful limitation. Those who prefer advanced scroll input options will also find the absence of a tilting or thumb scroll wheel restrictive, and anyone who wants to switch between configurations directly from the mouse will miss the lack of a profile switching button.

Final Verdict

The GravaStar Mercury M2 is a right-handed gaming mouse that builds a coherent case around flexibility and endurance, with tri-mode connectivity and a 70-hour battery life forming the core of its practical appeal. The PixArt PAW3395 sensor, wide DPI range, and 1000 Hz polling rate give it solid tracking credentials, while the lightweight 79 g build and use-while-charging support make it a reasonable companion for extended gaming sessions. Some users will find the absence of onboard memory profiles and a profile switching button limiting, and the right-handed-only design narrows its audience by default. For the right-handed gamer who values wireless versatility and long battery endurance above all, the Mercury M2 delivers a well-rounded and capable package.
