## Long description

REDRAGON Origin M903 is a wired right-hand gaming mouse designed for responsive pointer control in FPS, MOBA and general PC gaming. It uses an optical RDN Origin sensor with adjustable resolution up to 4000 DPI, a USB Type-A connection and an ergonomic black housing. The mouse offers eight physical buttons, a scroll wheel with color indication for DPI levels, five customizable profiles stored in onboard memory and a set of removable lead weights to tune balance and feel.
Advantages
The optical sensor supports fine DPI adjustment in 100 DPI steps from 100 to 4000 DPI and captures up to 6000 frames per second, enabling reliable tracking at high speed and acceleration up to 20 G. Adjustable report rate (125, 250, 500 or 1000 Hz) and programmable buttons let you align responsiveness and controls to your play style. Onboard memory stores up to five profiles so settings travel with the mouse, and the MODE button on the underside provides quick profile switching with distinct backlight color feedback. Included removable weights and an ergonomic right-hand form factor allow physical and balance customization for extended gaming sessions.
Suitable for
First-person shooters (FPS) requiring precise aim and fast tracking
Multiplayer online battle arena (MOBA) games with multiple programmable commands
General PC gaming where wired low-latency control is preferred
Users seeking an ergonomic right-handed mouse with adjustable weight and profiles

How to use
Connect the mouse to a free USB Type-A port on your computer and allow the operating system to recognize the device. Use the included software or on-mouse controls to set DPI values, assign functions to the eight programmable buttons and create up to five profiles. Store preferred profiles to the mouse memory so they remain available when the mouse is moved between systems. Use the MODE button on the underside to switch profiles during play; the scroll wheel backlight will indicate the current DPI level or profile color. Install weights into the designated compartment to achieve the desired balance.
Usage recommendations
For consistent tracking, use a flat, low-pile mouse pad and set DPI and report rate according to the game's sensitivity system. Save frequently used configurations to the onboard profiles and assign critical commands to easily reachable buttons for faster in-game response.
