ELECOM Wireless Mouse Medium 3 IR Power Black (Receiver Included), Size, Buttons, Silent, Sensor, Saving, M-IR07DRSBK

This wireless mouse features silent switches on the left and right buttons and the scroll wheel, providing a satisfying click feel without the annoying clicking sound, allowing for quiet use. This is an IR LED mouse that uses low-power infrared LEDs. Because it consumes less power than mice using Blue LED or laser, it can be for approximately 2.5 years without replacing the battery. This wireless type uses the 2.4GHz band and can be within a range of approximately 10m on non-magnetic surfaces and approximately 3m on magnetic surfaces such as steel desks. (According to our research) It features a micro-receiver the size of a one-yen coin that is unobtrusive when plugged into a laptop's USB port and can be carried around while plugged in.
