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. It features a symmetrical design that allows for versatile grip. It features a 1200 count resolution for smooth operation. The wireless system 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.
