The E7 Wireless Mouse from IOGEAR is a 2.4GHz wireless mouse with a nano receiver that plugs into a USB port on your computer. You can use the mouse from up to 33' away from your computer. For convenience, the receiver can be stored inside of the battery compartment when you're not using it. The mouse features adjustable sensitivity, allowing you to select the one best for your application.
The mouse features a precision and gaming mode, and also an energy-saving mode. When you switch between these three modes, an LED shines on the scroll wheel. The mouse is powered by either one or two AA batteries (two are included). Using two ensures it will stay powered for up to a year and affords a more stable, weighted feel. To extend battery life, the mouse is automatically put to sleep when your hand is removed and wakes when touched.
