Thunderobot ML903 Pro

Manufacturer: Thunderobot

The Thunderobot ML903 Pro is a right-handed gaming mouse built around tri-mode connectivity, supporting USB wired, 2.4GHz wireless, and Bluetooth 5 operation. Weighing just 65 g, it offers a compact and lightweight form factor with RGB lighting and a rechargeable battery rated for up to 70 hours of use, with the added convenience of being fully usable while charging.

At its core, the ML903 Pro relies on the Pixart PAW3395 sensor, which supports a DPI range from 800 to 26,000 and tracks at speeds up to 650 IPS with a maximum acceleration of 50G. The mouse operates at a 4000 Hz polling rate and features five fully programmable buttons, including two side buttons and a dedicated DPI switching button. Its physical dimensions measure 124 mm in height, 63 mm in width, and 39 mm in thickness, and it carries a one-year warranty.

  • No tilting or thumb scroll wheel, reducing navigation flexibility
  • Does not include extra swappable weights for users who prefer a heavier feel
  • Warranty period is limited to one year
Who is this for?

This mouse is a solid fit for right-handed gamers who prioritize responsive, low-latency input, given its 4000 Hz polling rate and Pixart PAW3395 sensor with a wide DPI range up to 26,000. The tri-mode connectivity makes it equally practical for users who switch between wired and wireless setups, while the 70-hour battery life with pass-through charging suits those who need reliable wireless performance during long sessions. Users who value a lightweight form factor at 65 g will also find it comfortable for extended use without physical strain.

Who is this NOT for?

Left-handed users will find this mouse incompatible due to its strictly right-handed ergonomic design. Those who rely on onboard memory profiles to carry custom settings between systems will be disappointed, as the mouse stores no profiles on-device. Users who require advanced scroll wheel functionality — such as tilting or thumb-operated scroll wheels — for tasks like horizontal navigation or media editing will find the feature set lacking in that regard. Additionally, users who prefer to fine-tune the physical weight of their mouse will not find that option here, as no swappable weights are included.
