The CHERRY MW 2310 2.0 is a versatile 6-button wireless mouse with 2.4 GHz technology & an ergonomic design. Its nano USB (Universal Serial Bus) receiver is so small that it can safely stay inside the notebook even when youre on the move – the mouse is always ready for use. The CHERRY MW 2310 2.0 has an optical sensor with 3 adjustable resolutions (1000/1600/2400 DPI). Using the DPI switch on the top of the mouse, the resolution can be selected at the touch of a button. An LED indicates the selected DPI. The technical concept makes the successor to the legendary CHERRY MW 2310 especially energy-efficient. With just one set of the supplied batteries (2 x AA), the mouse can be operated for up to 3 years before they have to be changed. The mouse has an On/ Off switch on the bottom so it can be switched off completely when not in use.
