Single mode is a working mode for me: wired or wireless.
Dual-mode mouse, that is, there are two mouse positioning modes of laser and photoelectric, not two computers at the same time, but wired can be used, wireless can also be used, which greatly improves the convenience. The cable can be fixed to the chassis, and the mouse plug can be directly inserted and removed, which is convenient and durable.
Three modes refers to wired, Bluetooth, 2.4g (or other frequency bands) three modes.
Mouse support wireless, Bluetooth, wired is three modes.
