With this mouse you always have the right ergonomic posture. Ergonomic: relaxed, neutral wrist and hand position. Unique: button instantly switches between right and left-handed use. Convenience: easy to use, familiar pen grip, 4 dpi settings. Mobile: wireless and most compact ergonomic mouse. Rechargeable: recharge whilst in use. Connection: wireless RF USB receiver. Using a mouse to navigate the cursor and activate icons is a precision task that demands a high degree of accuracy. Moving control of the mouse is most efficient in what is known as the precision grip (Napier, 1956) where index finger and thumb work closely together, and not by moving the whole arm from the shoulder (as in many so-called ergonomic mouse designs). The use of a precision mouse can also result in less muscle strain in the forearms because this involves less wrist extension (Kotani & Horii, 2003, Ulmann, et al., 2003).
