Adesso iMouse E90 Wireless Left-handed Ergonomic Optical Mouse - Black

This iMouse E9 Left-Handed Vertical Ergonomic Mouse is designed with a vertical orientation and a contoured shape that provides a uniquely comfortable user experience. Designed specifically for left-handers, this wrist-friendly contour support, you will hold your hand in a healthy “handshake position” which is the neutral position of your forearm. This feature prevents your forearm from twisting when using this vertical ergonomic mouse. Featuring two ergonomic buttons that are located conveniently on the side of the mouse allowing seamless back and forth browsing. The 800/1200/1600/2400 switchable DPI control provides four levels of mouse cursor speed that works 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 mouse pad.\n\nWith this wrist-friendly contour, you will hold your hand as “handshake position” which is also the neutral position of your forearm.\n\nNormally, your forearm will be twisted in order to be flat on the supporting surface when using regular mouse. However, this posture will strain your muscles and then lead to wrist pain while using the normal mouse constantly without rest. That’s where Adesso iMouse E9 becomes helpful.
