Polling Rate
The mouse operates at a 125Hz polling rate across all three modes (2.4G, BT1, BT2), ensuring responsive and smooth cursor movement.
Backlight Modes
The Cousopo T90 features an RGB backlight with 11 different modes. You can cycle through these modes using a dedicated button (refer to the mouse diagram in the physical manual for exact button location, often near the scroll wheel or on the side). This allows you to customize the aesthetic of your gaming setup.
Silent Click Design
The mouse is designed with silent left and right click buttons, reducing noise during use, which is ideal for quiet environments or late-night gaming sessions.

Maintenance
Cleaning
To clean the mouse, use a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the mouse's internal components. Avoid using harsh chemicals or abrasive cleaners.
Battery Care
To prolong battery life, avoid fully discharging the mouse frequently. Charge it when the battery indicator is low. If storing the mouse for an extended period, charge it to about 50% and store it in a cool, dry place.
