This IOGEAR's USB RF Wireless Optical Mini Mouse is an excellent tool for mobile professionals. RF- or 'radio frequency'- is a power-efficient wireless technology that allows you the freedom of a wireless mouse. The small and portable design saves precious space in your mobile work area, and it is one less tangled wire in your laptop carrying case. The ergonomically contoured design and optical sensor offer comfortable use on most surfaces, without the need for a mouse pad. This mouse features 800 dpi resolution, meaning it offers twice the accuracy of typical mouse movement, which is ideal for graphic designing or any other type of computing where precision matters. This unit is USB ready, Plug-n-Play and hot pluggable. For added convenience, the RF Mini Mouse also features a power On/Off switch to avoid battery drainage during travel, and a USB charger cable for convenient charging through the USB port on laptops. This mouse is the ultimate tool for the road warrior of today.
