UGREEN 90855 Wireless Bluetooth Mouse 2.4 GHz Ergonomic 4000 DPI Trackball Mouse for Tablet Laptop PC

UGREEN 90855 operates as a dual-mode wireless mouse with 2.4 GHz and Bluetooth connectivity options. Users switch between connection types based on device requirements. Compatible with tablets, laptops, and desktop PCs. Two wireless modes on one mouse body mean one device covers multiple connection scenarios.

The DPI rating sits at 4000. That sensitivity level covers both precision tasks and faster cursor movement across larger screens. Mouse tracks using trackball operation mode rather than an optical or laser sensor underneath. The trackball mechanism differs from standard mice in how cursor movement registers.

Hand orientation designed for both left- and right-hand users. The ambidextrous shape works regardless of dominant hand. No separate left-hand or right-hand model needed. UGREEN built the 90855 for either hand without shape bias toward one side.

The button count is listed at three. The roller count is also three. Standard click functions plus scrolling are covered through this configuration. Six mute buttons referenced in product naming indicate quiet click operation during use. Button presses stay silent compared to standard click mechanisms.

Ergonomic design noted in product specifications. The shape follows ergonomic principles for hand positioning during extended use periods.

Power runs on battery. No built-in rechargeable cell mentioned in specifications. The USB interface type is listed for the 2.4GHz wireless receiver that plugs into the host device. Bluetooth mode connects directly without the receiver occupying a USB port.

Gross weight measures 100 grams with packaging included. The actual mouse weight falls under that figure once removed from the box.
