Bring more natural control to office, home, and creative desk work with the seenda MOU-302 Bluetooth ergonomic vertical mouse. The green-purple design combines a right-hand vertical shape, quiet main clicks, a built-in volume knob, and three wireless channels for office professionals, remote workers, content planners, and students handling documents, meetings, media, and daily computer tasks. Connect one computer through the 2.4G USB receiver and two additional devices through Bluetooth. Use the button on the bottom to switch between a desktop, laptop, MacBook, iPad, or Android tablet—useful for hybrid workstations, home offices, classrooms, and multi-device creative desks. Forward and backward buttons are designed for Windows and do not function on macOS. The vertical shape supports a more neutral wrist and forearm position during browsing, spreadsheets, research, content review, and long desk sessions. It is recommended for small to medium right hands; very small or large hands should check the size guide. Turn the volume knob to adjust system volume and press it to play or pause media during video meetings, presentations, or content review. Nearby controls may need a brief adjustment period. Quiet left and right clicks help reduce distractions in offices, shared workspaces, dorms, and late-night study. Adjustable 1000/1600/2400 DPI supports documents, browsing, and everyday creative tasks, but not competitive gaming or professional high-polling precision. The built-in 500mAh battery recharges by USB-C and may provide up to two months of typical use depending on settings and workload. Includes a USB receiver, Type-C cable, manual, and 24-month warranty.
