The Logitech's M185 Wireless Mouse is an affordable, straightforward, comfortable mouse for use with your laptop or desktop computer. This mouse is designed to work with either your right or left-hand and features right and left-click buttons as well as a scroll wheel. The mouse also comes with a USB nano receiver that fits into a USB port on your computer. That receiver emits a wireless signal on the 2.4GHz band and connects with the mouse, so that you can work without wires. Plus, the receiver is plug-and-play, so it will work on virtually all computers without the need to install software or drivers. The mouse comes with a pre-installed AA battery and can work for as long as 12 months. Plug-and-Forget Nano Receiver The included USB receiver is so small and unobtrusive that you can plug it into a USB port and forget about it. Plus, you can say good-bye to worries about lost receivers. 1-Year Battery Life You can go for a year without battery hassles. The On/Off switch and smart sleep mode help conserve power. Please note that battery life may vary based on user and computing conditions. Advanced 2.4GHz Wireless Connectivity You get the reliability of a cord with wireless convenience and freedom-fast data transmission and virtually no delays or dropouts. Plug-and-Play Simplicity No software, no hassles - simply plug in the tiny nano receiver and start using your mouse right away. Comfy, Contoured Shape The contoured design feels good in either hand and offers more comfort than a touchpad.
