The Adesso iMouse E20 2.4GHz RF Wireless Vertical Ergonomic Laser Mouse provides you with wireless convenience and the freedom of a smooth connection for up to a 30 ft. range without tangled cables. This ergonomic mouse is designed with a vertical orientation and a contoured shape that provides a uniquely comfortable user experience. With this wrist-friendly contour support, you will hold your hand in a healthy "handshake position," which is the neutral position of your forearm as opposed to the "twisted forearm" position as with a regular mouse. Two Internet buttons are conveniently located on the side of the mouse for back and forward page browsing. The switchable DPI button on the top provides multiple levels of mouse cursor speed that are useful in different environments. The advanced optical sensor technology keeps the mouse precisely on point and lets you work on most glass, wood, marble, and leather surfaces without a need of a mouse pad. Finally, the mouse is plug and play and requires no drivers. Simply plug the USB receiver into any available USB port and get ready to enjoy the freedom of a comfortable and wireless mouse experience
