Wireless IR LED Mouse (3 Buttons) Black with Silent M-IR07DRSBK 1 Piece

This wireless mouse uses silent switches for the left, right and wheel buttons, providing a firm feel when pressed without annoying clicking noise, allowing you to use it quietly. This is an IRLED mouse that uses a low-power infrared LED. Because it consumes less power than mice that use Blue LED or lasers, it can be used for approximately 2.5 years without needing to change the batteries. It is a wireless type that uses the 2.4GHz band and can be used within a range of about 10m on non-magnetic surfaces, and about 3m on magnetic surfaces such as steel desks (according to ELECOM). It uses a micro receiver the size of a 1 yen coin that can be carried around while attached, so it doesn't get in the way when connected to the USB port of a laptop. The receiver can be stored inside the mouse body, making it convenient to carry and reducing the risk of losing the receiver. It has a resolution of 1200 counts for smooth operation. It features a symmetrical design that allows you to hold it in any way you like. There is a power switch on the back of the unit to prevent battery consumption when not in use.
