Ergonomic wireless mouse with optical sensor for Windows XP or later versions of Windows. The mouse connects to a computer with a discrete USB receiver whose minimal size makes it suitable for laptops.
You do not need to install any drivers, just plug the receiver into an available USB port on your computer and insert
a AA battery.You can press the DPI button to switch between 800, 1200 or 1600 dpi sensor resolution. Higher resolution/dpi allows you to control the cursor with larger precision.´
