Comfortability meets performance with the J-Tech Digital V638R Ergonomic Vertical Mouse. The V638R is perfect for anyone who experiences wrist and hand fatigue or discomfort when using a traditional mouse. The vertical design reduces the torsion of the forearm and wrist caused by the ergonomics of a traditional mouse. The DPI-variable, high-precision optical sensor can result in less hand movement and in turn reduce fatigue when working for extended periods of time.
