GravaStar Mercury M2 Wireless Gaming Mouse with 5 Dynamic Lightsync RGB

The GravaStar Mercury M2 is a wireless gaming mouse built for players who want precise control, flexible connectivity, and a look that stands out on the desk. It targets both competitive and casual gamers who are tired of choosing between speed and style, or between wired reliability and wireless freedom.

At the core of the M2 is the PAW3395 sensor, which supports up to 26,000 DPI and a 1,000 Hz polling rate. In practical terms, that polling rate means the mouse reports its position to your PC up to 1,000 times per second, so even quick, small movements register accurately rather than getting smoothed over. The DPI ceiling is high enough that you can dial it down for slow, precise aiming or push it up for fast sweeping motions, all through the companion software. The M2 connects three ways: 2.4G wireless for low-latency play, Bluetooth for casual or multi-device use, and a wired connection as a reliable fallback. The extended battery life means you are not constantly hunting for a charging cable mid-session, though the listing does not specify exactly how many hours you get per charge.

The hollowed-out shell is one of the M2's most distinctive traits. The cutouts reduce the amount of material contacting your palm, which the design is intended to improve airflow and keep your hand cooler. Whether that matters to you depends on how long your sessions run and how warm your hands tend to get. It also gives the mouse a visually striking look that sets it apart from solid-shell designs. Five programmable buttons work alongside the software to let you assign macros or remap functions, which is useful for MMO players or anyone who relies on complex key combinations. The GLOWSYNC RGB system offers five dynamic modes, and you can build custom lighting profiles in the software.

A few things are worth noting before you buy. The hollowed design, while functional, is unconventional and may feel odd to users who prefer a solid, palm-filling shell. Full customization of lighting, DPI, and button mapping requires installing the companion software, so out-of-the-box flexibility is limited. The listing does not detail the weight, exact dimensions, or what the shell material is, so shoppers with strong preferences on those points may want to seek out that information separately.

Verdict: The M2 is a capable option for gamers who want a high-performance sensor, true wireless versatility, and a distinctive look in one package. It suits players who will take the time to configure the software and who appreciate a cooler-running, open-shell design. If you prefer a conventional solid body or need out-of-the-box simplicity, it may not be the right fit.

A great fit if you:

• Want the flexibility to switch between 2.4G wireless, Bluetooth, and wired on the same mouse
• Play for long stretches and want a design that reduces heat buildup at your grip
• Like to personalize your setup with custom RGB lighting profiles and programmable macros
• Need a high-sensitivity sensor that can be tuned precisely through software

Consider something else if you:

• Prefer a solid, fully enclosed shell and a traditional palm-filling feel
• Want a plug-and-play mouse that works fully without any software installation

Can I use this mouse without installing any software?
The M2 will connect and function as a mouse right away, but customizing DPI settings, button macros, and lighting profiles requires the companion software. Basic use is plug-and-play; advanced configuration is not.

What wireless options does the M2 support?
It supports three connection modes: 2.4G wireless, Bluetooth, and a standard wired connection. You can choose whichever suits your setup or switch between them as needed.

How many buttons can be programmed?
The M2 has five programmable buttons. Using the software, you can assign macros, remap functions, and adjust DPI levels to fit your preferred play style.

What sensor does the M2 use, and what is the maximum DPI?
It uses a PAW3395 sensor with a maximum sensitivity of 26,000 DPI and a 1,000 Hz polling rate, which means it updates your cursor position up to 1,000 times per second.
