Name: GravaStar Mercury X Pro
Brand: GravaStar
SKU: 3985

Manufacturer: GravaStar

The GravaStar Mercury X Pro is a lightweight wireless gaming mouse built for right-handed users who want a compact, capable peripheral without unnecessary bulk. Tipping the scales at just 49 g, it offers a streamlined form factor with dimensions of 124.6 mm in length, 63.5 mm in width, and 40.5 mm in thickness, making it a notably compact option in the gaming mouse category. It connects via 2.4 GHz wireless, USB, or Bluetooth 5.2, giving users flexibility depending on their setup, and it supports use while charging so sessions are rarely interrupted.

Under the hood, the Mercury X Pro relies on the PixArt PAW3950 sensor, which covers a DPI range from 50 to 32000 and tracks at speeds up to 650 IPS with a maximum acceleration of 50 G. The polling rate reaches 8000 Hz, and the mouse includes six buttons in total, five of which are programmable, along with dedicated DPI and profile switching buttons. Battery life is rated at 200 hours on a single charge, and the rechargeable cell is built in rather than removable. RGB lighting is present, and the included cable measures 1.8 m in length. GravaStar backs the mouse with a one-year warranty.

Pros

The 8000 Hz polling rate ensures very frequent position reporting, which benefits fast-paced gaming scenarios
A DPI range spanning from 50 to 32000 provides a wide degree of sensitivity customization to suit different tasks and preferences
Rated battery life of 200 hours on a single charge means extended use between recharging sessions
Three connection options — 2.4 GHz wireless, USB, and Bluetooth 5.2 — offer flexibility across different setups and devices
At 49 g with compact dimensions, the mouse is light and easy to handle during extended sessions
The mouse can be used while charging, preventing downtime when the battery runs low

Cons

Designed only for right-handed users, limiting accessibility for left-handed users
No onboard memory profiles means settings cannot be stored directly on the mouse for use across different systems
The scroll wheel does not tilt and there is no thumb scroll wheel, reducing navigation options
No extra weights are included, so the 49 g weight cannot be adjusted by the user
The warranty period is limited to one year
The battery is built-in and non-removable, so it cannot be swapped out if it degrades over time

Who is this for?

This mouse is a strong fit for right-handed gamers who prioritize low weight and high responsiveness, as the 49 g build combined with an 8000 Hz polling rate caters well to fast, precise movement in competitive gaming. The triple connectivity options — 2.4 GHz wireless, USB, and Bluetooth 5.2 — also make it practical for users who switch between devices or setups regularly. Additionally, the 200-hour battery life suits those who need a reliable wireless peripheral for long sessions without frequent interruptions.

Who is this NOT for?

Left-handed users will find this mouse unsuitable given its strictly right-handed ergonomic orientation. Those who rely on onboard memory profiles to carry customized settings between systems will also find it limiting, as the mouse stores no profiles on-board. Users who prefer a heavier or weight-adjustable mouse for a more anchored feel during slow, deliberate movements will be constrained as well, since no extra weights are included and the fixed 49 g cannot be modified.

Final Verdict

The GravaStar Mercury X Pro presents a well-defined specification set aimed squarely at right-handed gamers who want a lightweight, wireless-first peripheral. Its standout characteristic is the combination of a 49 g body with an 8000 Hz polling rate, which together form the core of its competitive gaming appeal. The broad DPI range, extended battery life, and flexible connectivity round out a feature set that covers most practical gaming needs without unnecessary complexity. Where it falls short — no onboard memory, no adjustable weight, and a right-hand-only design — those limitations are consistent trade-offs for a mouse of this form factor. For right-handed users seeking a capable, low-latency wireless gaming mouse with dependable battery endurance, the Mercury X Pro represents a coherent and purposeful choice.
