The Adesso iMouse E2 Vertical Ergonomic Laser Mouse is designed with a vertical orientation and a contoured shape that provides a uniquely comfortable user experience. With its 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.

• User can quickly & easily adjust dpi resolution (400dpi/800dpi/1600dpi/3200dpi) with switch located beside thumb
• Advanced laser sensor allows greater precision in mouse navigation, increases battery life & works on more surfaces than an optical mouse
